    777:
    25x10=250,
    250+9=259,
    259x3=777.

    1. (5+8)x75+6+9=990 or (5x(9+9)+75)x6=990
    2. (1+75)x10+3x4=772-50=722
    3. (5x50)-(9-6)x8=226

    For 226 I got it very simple
    5*50=250 take away
    (9+9+6). No-one seems to have done this way.

    So, do people know about 37 X 21 or is a case of running through different options in your head?

      It’s just knowing times tables I guess mate. Takes months of practise 😂 I saw the 777 solution as knowing that 3 x 250 is 750 and needed to find that additional 27 to solve the solution. I know that 3 x 9 = 27, so what I did was:
      (25 x 10) + 9 = 259
      259 x 3 = 777
      I’m an engineering student so this level of times tables is useless to me. Normally I would just use MATLAB 🙈😂

      likely 777=7*111 and easy to see 111 divisible by 3, 3*37

    722 is also
    (10+3) * 50 = 650
    +75+1-4

    In the first numbers round, I saw both contestants' solutions, but I also had this pair of related solutions. Because of the presence of the 75 and the 5, you can send the numbers up into four digits if you like, as follows:
    9 x 8 = 72
    72 - 6 = 66
    75 x 66 = 4950
    4950 / 5 = 990
    But you can also do the equivalent thing with this set of numbers as follows:
    75 - 9 = 66
    9 + 6 = 15
    66 x 15 = 990
    Which shows you the trick of what 75 / 5 is.
    In the second numbers round, I thought Ronan's solution was going to be my alternative solution, because I thought the following solution was much more intuitive:
    10 - 1 = 9
    75 x 9 = 675
    675 + 50 = 725
    725 - 3 = 722
    And I also had these ones:
    10 x 50 = 500
    75 - 1 = 74
    74 x 3 = 222
    500 + 222 = 722
    75 - 1 = 74
    74 x 10 = 740
    50 + 4 = 54
    54 / 3 = 18
    740 - 18 = 722
    In the third numbers round, I saw both contestants' solutions (although with Ronan's I just did 50 x 5 - 9 - 9 - 6 = 226), but I also had these solutions:
    9 - 6 = 3
    50 - 3 = 47
    47 x 5 = 235
    235 - 9 = 226
    9 - 6 = 3
    9 x 3 = 27
    27 - 5 = 22
    22 x 8 = 176
    176 + 50 = 226
    In the final numbers round, I saw Ronan's solution because I always factor where possible, but I also had these:
    25 x 10 = 250
    250 + 9 = 259
    259 x 3 = 777
    25 x 6 x 5 = 750
    9 x 3 = 27
    750 + 27 = 777
    25 - 10 = 15
    15 x 9 = 135
    135 - 5 = 130
    130 x 6 = 780
    780 - 3 = 777

    226:
    50 * 5 = 250
    9 - 6 = 3
    8 * 3 = 24
    250 - 24 = 226
    50 * 5 = 250
    250 - 9 - 9 - 6 = 226
    50 + 6 - 9 = 47
    47 * 5 = 235

    My solutions:
    ((9-8+6)x5+75)x9 = 990
    (50x10)+(75x3)-4+1 = 722
    (50x5)-(8x(9-6)) = 226
    (25x6x5)+(9x3) = 777

    I don't really get the solution of the older contestant in the first round. He used only one of the 9s. Is that legal in this game?

      @santerikoho1579 Год назад +7

      Yeah you dont have to use all numbers. If the target is 300 and you see 50 and 6 on the board, you dont have to use four other numbers.
