Here's a valuable tip for questions and problems like these. Add other brackets wherever they apply. If it makes it simpler, change the look of the brackets at each level. Where there are +/-signs and ÷/x within the same brackets, extra brackets would help. 9(3+3x2) is more clearly written as 9(3+[3x2]) more clearly read as 9x(3+ 6), then 9x9, which equals 81
Larsdal 5+5/5*5=5+1*5=10.thats when we divide first. Now let us multiply first 5+5*5div 5=5+25/5=5+5*1=10. Eg 10div2*3=5*3=15.now 10*3=30/2=15.you are making the mistake of saying 2*3=6but it is div 2*3=3/2.Hope this clears your confusion
The 5 x (5 + 5 ÷ 5 x 5) is an example of why I'm not too fond of PEMDAS. Yes, the correct answer is 50. But! If you follow PEMDAS strictly, then the result is 26. M (for multiplication) is (in peMDas) before D (for division) -> But the reality is they have the same priority, and thus have to be evaluated in order -> Which is why PEMDAS is wrong!
BODMAS acronym ie B - Brackets, O - Order of powers or roots, D - Division, M - Multiplication A - Addition, and S - Subtraction this is what I was taught at school, and yes Division and Multiplication have the same importance, so should be done in appearance order yes 50 is correct I feel we are slipping further and further into the world of 1984
PEMDAS and BODMAS both are flawed acronyms. The order of the letters let you think, that either Multiplication or Division (depending on the acronym) has a higher priority, but in reality have the same priority. In Germany, we learn "Punkt- vor Strichrechnung" (literal " dot calculation before line calculation"). Our Multiplication symbol is the "⋅" (vertical centered dot) and the Division symbol is ":" (colon), whereas Addition/Subtraction have the same symbols "+" and "-" as in English. As you see both Multiplication and Division have symbols with dots in it and according to the rule mentioned earlier, they have priority before Addition and Subtraction but not before each other.
@@robertveith6383 And exactly that is the problem. People learn that acronym and forget that multiplication/division and addition/subtraction have the same priority. If you then follow it strictly, you do the wrong order. That's why those acronyms are flawed.
You are talking about PEMDAS Your primary school teacher taught you that and you gobbled it without really understanding it. You are now a mathematician but you don't know what the S in Pemdas stands for. Would love to hear your answer. monkey see monkey do

@FunWithMaths -- You did the last problem wrong. After you 3, then the sdditive inverse of that is -3 for the answer, not 3.
81 for the first one, 24 for the second which is also 4!, 50, for the third one, 3 for the last one

An addictive inverse. Is an inverse you simply cannot resist.
Comes up with the answer "3" for the last calculation, then uses "-3" to finish off the question!
🍌🙄
Mr William. You hit the nail on the head instead of listening to this guy's crap.
81
(3×2)=6
(3+6)=9
(9)9=81
24
8x4=32
32÷2=16
16+8=24

Factorial 4.

Thats my problem with ÷ symbol, just write X 1/x instead of ÷x. Much clearer that way

No, if you follow it strictly, it works, because it is understood to be this: PE(MD)(AS).

15 for pemdas 1st guestion
please show your work. Your answer is incorrect but I would really like to kknow how you arrived at that.
You are talking about PEMDAS
Your primary school teacher taught you that and you gobbled it without really understanding it. You are now a mathematician but you don't know what the S in Pemdas stands for. Would love to hear your answer. monkey see monkey do
Were you taught conversation and dialog ?
you are to question the idea or the thought
not the person
