Please Excuse My Dear Aunt Sally.

400

Tell what 5 ³ really means.

It means 5 x 5 x 5

From left to right (like we read)

Fix my Mistake

100

9 - 3 x 2=12

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

200

5 ² + 1=11

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

300

14  - 2 x 7 = 84

Multiplication comes first.

14 - 14 = is not 84. Correct answer is 0

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.
