The first round reminds us of the best advice: First, divide by the numbers you already have. 8 gives 68, 4 gives 136 3 gives 180 2 gives 271 Then check if you can easily make one of those from the remaining numbers. If these steps fail, they didn't take much time, and you can look for other avenues. In this case, both 68 and 136 work. _
Monday (13/2/2023) ----------------- For the first round, it is noticed that 550 = 25 x 22, so another solution to obtain the target is: 25 - 3 = 22 100 / 4 = 25 25 x 22 = 550 550 - 8 = 542 Another simple solution can be: 8 - 3 = 5 5 x 100 = 500 25 - 4 = 21 21 x 2 = 42 500 + 42 = 542 For the second round, in addition to Andrew's solution, notice that 615 = 3 x 5 x 41, one possible factoring solution is: 7 x 5 = 35 35 + 6 = 41 25 - 10 = 15 41 x 15 = 615 For the third round, in addition to Andrew's obvious solution, an alternative to get from 700 is: 7 x 100 = 700 75 / 3 = 25 25 + 5 = 30 700 - 30 = 670 Besides, since 675 = 75 x 9, another easy solution is: 75 x 9 = 675 675 - 5 = 670 Also, it is found that 670 is divisible by 5, so a possible factoring solution is: 75 / 3 = 25 25 + 9 = 34 100 + 34 = 134 134 x 5 = 670 The last round is a bit tricky. I got the same as Rachel’s solution, but cannot find any alternative way of obtaining the target.
Tuesday (14/2/2023) ------------------ The first round is easy. In addition to the contestants' obvious solutions, there are several alternative solutions: 3 + 6 = 9 9 x 25 = 225 225 + 10 = 235 235 x 2 = 470 50 x 2 = 100 100 - 6 = 94 25 - 10 = 15 15 / 3 = 5 94 x 5 = 470 50 + 25 + 3 = 78 78 x 6 = 468 468 + 2 = 470 For the second round, in addition to Rachel's solution, there is another alternative from 936: 75 + 3 = 78 6 x 2 = 12 78 x 12 = 936 25 - 10 = 15 936 + 15 = 951 The last two rounds are too easy and there are not many meaningful alternatives.
Wednesday (15/2/2023) -------------------- For the first round, in addition to Rachel's solution, an alternative solution is: 100 - 3 = 97 97 x 7 = 679 679 + 6 = 685 The second round is impossible. Adam's solution is the best that we can get, and this is the only way. The third round is easy since there is a 10, and the target is divisible by 10. Apart from the obvious solution, some more alternatives can be found: 25 + 50 = 75 75 x 7 = 525 525 - 5 = 520 6 + 7 = 13 50 - 10 = 40 13 x 40 = 520 The most intuitive ways to obtain the target in the last round are from 170: 6 x 3 = 18 5 - 4 = 1 18 - 1 = 17 17 x 10 = 170 170 - 3 = 167 3 x 10 = 30 30 + 4 = 34 34 x 5 = 170 170 - 3 = 167 In addition to Adam's solution, there are a couple of alternative solutions as well: 6 x 10 = 60 60 - 3 = 57 57 x 3 = 171 171 - 4 = 167 3 x 10 = 30 30 + 6 + 5 = 41 41 x 4 = 164 164 + 3 = 167
Friday (17/2/2023) ------------------ For the first round, the closest that we can get is 948, and there are a couple of ways: 75 x 2 = 150 150 + 7 + 1 = 158 158 x 6 = 948 75 x 7 = 525 525 - 1 = 524 524 x 2 = 1048 1048 - 100 = 948 75 - 2 = 73 6 + 7 = 13 73 x 13 = 949 949 - 1 = 948 The second round is much easier than the first round, since there is 825 = 3 x 11 x 25. However, I cannot find any alternative other than making 75 by 25 + 50. For the third round, the target is divisible by 7, so a factoring solution can be found: 100 - 10 = 90 90 + 2 = 92 92 x 7 = 644 The target in the last round is divisible by 3, so one possible factoring solution is: 50 / 25 = 2 75 - 2 = 73 73 x 3 = 219 In addition, there are a couple of alternative solutions: 25 x 9 = 225 225 - 6 = 219 6 x 50 = 300 300 - 75 - 9 = 216 216 + 3 = 219
Monday Countdown In the first round, I saw Rachel's solution and also had: 8 + 3 = 11 25 x 11 = 275 275 - 4 = 271 271 x 2 = 542 100 x 3 = 300 300 - 25 = 275 275 x 2 = 550 550 - 8 = 542 In the second round, I saw Andrew's solution and also had: 7 x 2 = 14 14 + 6 + 5 = 25 25 x 25 = 625 625 - 10 = 615 7 x 5 = 35 35 + 6 = 41 25 - 10 = 15 41 x 15 = 615 In the third round, I saw Andrew's solution, but also had this more direct path: 75 x 9 = 675 675 - 5 = 670 And these more complex ones: 100 - 3 = 97 97 x 7 = 679 679 - 9 = 670 100 x 7 = 700 9 - 3 = 6 6 x 5 = 30 700 - 30 = 670 75 / 3 = 25 100 + 25 + 9 = 134 134 x 5 = 670 In the fourth round, I saw Rachel's solution, but it's the only one.
Thursday Countdown I saw Rachel's solution, and there's this elaboration on it that allows for a fancy alternative: 100 + 75 + 1 = 176 176 - 6 = 170 170 x 7 = 1190 1190 / 5 = 238 Since you're dividing by 5, taking off 5 before dividing is equivalent to subtracting 1. And this one, which also uses the factors in a disguised way: 75 - 7 = 68 100 / 5 = 20 20 + 1 = 21 68 x 21 = 1428 1428 / 6 = 238 Here 6 is 3 x 2, so when dividing by 6 after multiplying 68 x 21, the 2 cancels with the 68 to make 34 and the 3 cancels with the 21 to make 7. Therefore it too is 34 x 7 = 238. In the second round, I saw Rachel's solution, but I also had this solution from factoring (17 x 11 x 3 = 561): 7 x 6 = 42 75 - 42 = 33 25 - 8 = 17 33 x 17 = 561 And I also had this alternative: 25 - 1 = 24 24 / 6 = 4 75 + 4 = 79 79 x 7 = 553 553 + 8 = 561 In the third round, I saw Peter's solution and also had these: 75 + 6 + 1 = 82 82 x 8 = 656 656 + 50 = 706 706 - 3 = 703 75 + 50 = 125 125 - 8 = 117 117 x 6 = 702 702 + 1 = 703 In the final round, I saw Peter's solution and also had this four-small: 6 + 5 + 3 = 14 14 x 10 = 140 And with the 25 and 50 it was just as easy: 50 x 3 = 150 150 - 10 = 140 25 x 6 = 150 150 - 10 = 140 50 + 25 = 75 75 - 5 = 70 6 / 3 = 2 70 x 2 = 140 50 x 25 = 1250 1250 + 10 = 1260 6 + 3 = 9 1260 / 9 = 140
Friday Countdown In the first round, my solution for one above was: 75 x 2 = 150 150 + 7 + 1 = 158 158 x 6 = 948 And for one below: 75 x 7 = 525 525 + 1 = 526 526 x 2 = 1052 1052 - 100 - 6 = 946 In the second round, I saw Rachel's solution, except that I did 50 + 25 to make 75 instead of multiplying 25 x 3. However, I also had these solutions: 50 - 4 = 46 25 - 7 = 18 46 x 18 = 828 3 - 2 = 1 828 - 1 = 827 25 + 2 = 27 27 x 4 = 108 108 + 3 = 111 111 x 7 = 777 777 + 50 = 827 In the third round, I saw the contestant's solution, but there was a more direct way by factoring (23 x 7 x 2^2 = 644): 10 - 2 = 8 100 - 8 = 92 92 x 7 = 644 And a couple of other ways are: 100 x 2 = 200 200 - 2 = 198 10 - 7 = 3 198 x 3 = 594 594 + 50 = 644 50 + 10 = 60 60 x 7 = 420 420 + 2 = 422 422 - 100 = 322 322 x 2 = 644 In the fourth round, it's one of those boring three-large games where there are several obvious answers and no real scope for more interesting solutions. Other obvious solutions are: 50 / 25 = 2 75 - 2 = 73 73 x 3 = 219 25 x 9 = 225 225 - 6 = 219 50 x 3 = 150 150 + 75 = 225 225 - 6 = 219 And the only potentially interesting solution I found was this: 75 x 6 = 450 450 - 9 - 3 = 438 438 x 25 = 10950 10950 / 50 = 219 But since you can just as easily do 50 / 25 = 2 and 438 / 2 = 219, there's no real point in it.
I really appreciate you posting these but the lazy me misses when you left in the 30 seconds because I don't want to pause, time myself, unpause 😄

8 gives 68,
4 gives 136
3 gives 180

Then check if you can easily make one of those from the remaining numbers.
If these steps fail, they didn't take much time, and you can look for other avenues.
In this case, both 68 and 136 work.

Monday (13/2/2023)
-----------------
For the first round, it is noticed that 550 = 25 x 22, so another solution to obtain the target is:
25 - 3 = 22
100 / 4 = 25
25 x 22 = 550
550 - 8 = 542
Another simple solution can be:
8 - 3 = 5
5 x 100 = 500
25 - 4 = 21
21 x 2 = 42
500 + 42 = 542
For the second round, in addition to Andrew's solution, notice that 615 = 3 x 5 x 41, one possible factoring solution is:
7 x 5 = 35
35 + 6 = 41
25 - 10 = 15
41 x 15 = 615
For the third round, in addition to Andrew's obvious solution, an alternative to get from 700 is:
7 x 100 = 700
75 / 3 = 25
25 + 5 = 30
700 - 30 = 670
Besides, since 675 = 75 x 9, another easy solution is:
75 x 9 = 675
675 - 5 = 670
Also, it is found that 670 is divisible by 5, so a possible factoring solution is:
75 / 3 = 25
25 + 9 = 34
100 + 34 = 134
134 x 5 = 670
The last round is a bit tricky. I got the same as Rachel’s solution, but cannot find any alternative way of obtaining the target.
Tuesday (14/2/2023)
------------------
The first round is easy. In addition to the contestants' obvious solutions, there are several alternative solutions:
3 + 6 = 9
9 x 25 = 225
225 + 10 = 235
235 x 2 = 470
50 x 2 = 100
100 - 6 = 94
25 - 10 = 15
15 / 3 = 5
94 x 5 = 470
50 + 25 + 3 = 78
78 x 6 = 468
468 + 2 = 470
For the second round, in addition to Rachel's solution, there is another alternative from 936:
75 + 3 = 78
6 x 2 = 12
78 x 12 = 936
25 - 10 = 15
936 + 15 = 951
The last two rounds are too easy and there are not many meaningful alternatives.
Wednesday (15/2/2023)
--------------------
For the first round, in addition to Rachel's solution, an alternative solution is:
100 - 3 = 97
97 x 7 = 679
679 + 6 = 685
The second round is impossible. Adam's solution is the best that we can get, and this is the only way.
The third round is easy since there is a 10, and the target is divisible by 10. Apart from the obvious solution, some more alternatives can be found:
25 + 50 = 75
75 x 7 = 525
525 - 5 = 520
6 + 7 = 13
50 - 10 = 40
13 x 40 = 520
The most intuitive ways to obtain the target in the last round are from 170:
6 x 3 = 18
5 - 4 = 1
18 - 1 = 17
17 x 10 = 170
170 - 3 = 167
3 x 10 = 30
30 + 4 = 34
34 x 5 = 170
170 - 3 = 167
In addition to Adam's solution, there are a couple of alternative solutions as well:
6 x 10 = 60
60 - 3 = 57
57 x 3 = 171
171 - 4 = 167
3 x 10 = 30
30 + 6 + 5 = 41
41 x 4 = 164
164 + 3 = 167
Thursday (16/2/2023)
-------------------
For first round, in addition to Rachel's solution, an alternative solution is:
75 / 5 = 15
15 + 7 + 1 = 23
23 x 6 = 138
138 + 100 = 238
For the second round, some alternative solutions are:
75 x 8 = 600
600 - 25 - 7 - 6 - 1 = 561
25 - 1 = 24
24 / 6 = 4
75 + 4 = 79
79 x 7 = 553
553 + 8 = 561
7 x 8 = 56
56 + 25 = 81
81 x 6 = 486
486 + 75 = 561
The third round is easy. However, I cannot find any alternative for this one, apart from Peter's solution.
The last round is the easiest round and there are lots of alternatives:
6 + 3 + 5 = 14
14 x 10 = 140
6 x 3 = 18
10 + 18 = 28
28 x 5 = 140
10 - 3 = 7
25 - 5 = 20
7 x 20 = 140
100 / 25 = 4
3 x 10 = 30
30 + 5 = 35
35 x 4 = 140
100 - 25 - 5 = 70
6 / 3 = 2
70 x 2 = 140
25 x 6 = 150
150 - 10 = 140
10 + 5 = 15
15 x 6 = 90
90 + 50 = 140
Friday (17/2/2023)
------------------
For the first round, the closest that we can get is 948, and there are a couple of ways:
75 x 2 = 150
150 + 7 + 1 = 158
158 x 6 = 948
75 x 7 = 525
525 - 1 = 524
524 x 2 = 1048
1048 - 100 = 948
75 - 2 = 73
6 + 7 = 13
73 x 13 = 949
949 - 1 = 948
The second round is much easier than the first round, since there is 825 = 3 x 11 x 25. However, I cannot find any alternative other than making 75 by 25 + 50.
For the third round, the target is divisible by 7, so a factoring solution can be found:
100 - 10 = 90
90 + 2 = 92
92 x 7 = 644
The target in the last round is divisible by 3, so one possible factoring solution is:
50 / 25 = 2
75 - 2 = 73
73 x 3 = 219
In addition, there are a couple of alternative solutions:
25 x 9 = 225
225 - 6 = 219
6 x 50 = 300
300 - 75 - 9 = 216
216 + 3 = 219
951 is also (75+3)*2*6 +25-10
10.27 . . James May has a nice shirt on
For the second numbers game today you have the alternative of (50+25)*(7+4)+2
561 is also 75*8 minus everything else
140=3×50-10=(50/5-6)×(25+10)=(10-3)×(25-5)=10×(6+5+3)=(50+25-5)×6/3=5×(25+3)

700 + 10 = 710
710 - 25 = 685
In the second round, I saw Adam's solution, but also had these two other solutions for 1 below:
100 - 75 = 25
25 x 25 = 625
50 + 1 = 51
51 x 4 = 204
625 - 204 = 421
4 + 1 = 5
75 x 5 = 375
375 + 50 = 425
100 / 25 = 4
425 - 4 = 421
In the third round, I saw both contestants' solutions and also had these from factoring (13 x 5 x 2^3 = 520):
50 - 10 = 40
7 + 6 = 13
40 x 13 = 520
50 + 25 = 75
75 - 10 = 65
7 + 6 = 13
13 - 5 = 8
65 x 8 = 520
10 x 7 = 70
70 - 50 = 20
20 + 6 = 26
25 - 5 = 20
26 x 20 = 520
In the final round, I saw Adam's solution and also had these:
10 x 5 = 50
50 + 6 = 56
56 x 3 = 168
4 - 3 = 1
168 - 1 = 167
10 x 4 = 40
40 - 6 = 34
34 x 5 = 170
170 - 3 = 167
5 x 3 = 15
6 - 4 = 2
15 + 2 = 17
17 x 10 = 170
170 - 3 = 167
Thursday Countdown
I saw Rachel's solution, and there's this elaboration on it that allows for a fancy alternative:
100 + 75 + 1 = 176
176 - 6 = 170
170 x 7 = 1190
1190 / 5 = 238
Since you're dividing by 5, taking off 5 before dividing is equivalent to subtracting 1.
And this one, which also uses the factors in a disguised way:
75 - 7 = 68
100 / 5 = 20
20 + 1 = 21
68 x 21 = 1428
1428 / 6 = 238
Here 6 is 3 x 2, so when dividing by 6 after multiplying 68 x 21, the 2 cancels with the 68 to make 34 and the 3 cancels with the 21 to make 7. Therefore it too is 34 x 7 = 238.
In the second round, I saw Rachel's solution, but I also had this solution from factoring (17 x 11 x 3 = 561):
7 x 6 = 42
75 - 42 = 33
25 - 8 = 17
33 x 17 = 561
And I also had this alternative:
25 - 1 = 24
24 / 6 = 4
75 + 4 = 79
79 x 7 = 553
553 + 8 = 561
In the third round, I saw Peter's solution and also had these:
75 + 6 + 1 = 82
82 x 8 = 656
656 + 50 = 706
706 - 3 = 703
75 + 50 = 125
125 - 8 = 117
117 x 6 = 702
702 + 1 = 703
In the final round, I saw Peter's solution and also had this four-small:
6 + 5 + 3 = 14
14 x 10 = 140
And with the 25 and 50 it was just as easy:
50 x 3 = 150
150 - 10 = 140
25 x 6 = 150
150 - 10 = 140
50 + 25 = 75
75 - 5 = 70
6 / 3 = 2
70 x 2 = 140
50 x 25 = 1250
1250 + 10 = 1260
6 + 3 = 9
1260 / 9 = 140
Friday Countdown
In the first round, my solution for one above was:
75 x 2 = 150
150 + 7 + 1 = 158
158 x 6 = 948
And for one below:
75 x 7 = 525
525 + 1 = 526
526 x 2 = 1052
1052 - 100 - 6 = 946
In the second round, I saw Rachel's solution, except that I did 50 + 25 to make 75 instead of multiplying 25 x 3. However, I also had these solutions:
50 - 4 = 46
25 - 7 = 18
46 x 18 = 828
3 - 2 = 1
828 - 1 = 827
25 + 2 = 27
27 x 4 = 108
108 + 3 = 111
111 x 7 = 777
777 + 50 = 827
In the third round, I saw the contestant's solution, but there was a more direct way by factoring (23 x 7 x 2^2 = 644):
10 - 2 = 8
100 - 8 = 92
92 x 7 = 644
And a couple of other ways are:
100 x 2 = 200
200 - 2 = 198
10 - 7 = 3
198 x 3 = 594
594 + 50 = 644
50 + 10 = 60
60 x 7 = 420
420 + 2 = 422
422 - 100 = 322
322 x 2 = 644
In the fourth round, it's one of those boring three-large games where there are several obvious answers and no real scope for more interesting solutions.
Other obvious solutions are:
50 / 25 = 2
75 - 2 = 73
73 x 3 = 219
25 x 9 = 225
225 - 6 = 219
50 x 3 = 150
150 + 75 = 225
225 - 6 = 219
And the only potentially interesting solution I found was this:
75 x 6 = 450
450 - 9 - 3 = 438
438 x 25 = 10950
10950 / 50 = 219
But since you can just as easily do 50 / 25 = 2 and 438 / 2 = 219, there's no real point in it.
