P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)

Here is a way to remember PEMDAS ( Please Excuse My Dear Aunt Sally) *Steven Birkmire*

18÷3×2+(10-3)² Step 1- Do what's in the parenthesis first. 10-3=7

Step 2- take the answer from the parenthesis and solve the exponents 7²=49

Step 3- move to the other side of the parenthesis' and start with multiplying 3x2=6

Step 4-take the answer you got from multiplying and divide it 18÷6=3

Step 5- take the answer you got when you solved the exponents and add it with the answer you got after you divided 49+3=52

Step 6- Go back and check your work and make sure you did everything and got the correct answer.

edited by gina 6. When simplifying an equations you may get two different answers if you do not follow the order of operations. o True example: 65-(-3)+74 x 2 (/)2= if you follow PEMDAS(the order of operations) you will get 142 if you dont you could get an entirely different answer.

Order of Operations 6. When simplifying an equations you may get two different answers if you do not follow the order of operations. o True o False Well this is of course true: Example this is an easy one. 4÷2+5•2-1 By following PEMDAS it's right which since there's no parentheses or exponents skip to multiplication and division. Well it doesnt matter which one goes first as long as one appears first so 4÷2 which equals 2 and 5•2 which equals 10. So the problem is now 2+10-1 and once more like multiplication doesn't matter addition or subtraction so 2+10 first then -1 so it gives you 11. But without PEMDAS and just do the problems by what comes first it would equal 13 which is incorrect.
