Please Excuse My Dear Aunt Sally.

200

Parentheses, Exponents, Multiplication OR Division, Addition OR Subtraction

Why is it important to know PEMDAS as a mathematician?

So everyone can solve every problem the same (correct) way.

400

Tell what 5 ³ really means.

It means 5 x 5 x 5

500

The problem was 20 - 5 x 2 + 3. My answer was 33. What did I do wrong?

I went from left to right without using the correct order of operations.

Fix my Mistake

100

3²  - 6 = 0

3 ²  = 9, not 6. Correct answer is 3

200

9 - 3 x 2=12

Correct answer is 3. Do x then -, not - then x.

300

5 ² + 1=11

5 ² = 25, not 10. Correct Answer is 26.

400

4 + 5 + 7 - 3 x 2 = 26

You need to follow PEMDAS and do x first. Correct answer is 10.

500

10 ³  = 30

10 ³  = 10 x 10 x10, which is 1000, not 30.
