Why is it important to know PEMDAS as a mathematician?
So everyone can solve every problem the same (correct) way.
"Less than" means what operation?
Subtraction
(8 x 7) ÷ 14 - 1

42 - 6 = 0
4 2 = 16, not 6. Correct answer is 10

14
What is the saying we use to remember the correct Order of Operations?
Please Excuse My Dear Aunt Sally.
"More than" means what operation?
Addition
(62 + 3) + 8 ÷ 2 =
76
4 + 5 + 7 - 4 * 2 = 26
You need to follow PEMDAS and do * first. Correct answer is 8
56 ÷ (4+4) - 32

Tell what 5 3 really means
It means 5*5*5
"Times" means what operation?
Multiplication
10 * (54 - 49) + 17=
67
10 5 = 50
10 5 = 10 * 10 *10 *10 * 10, which is 100000, not 50
12 + 22 x 32 - 42
