9 - 3 x 2=12

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

5 ² + 1=11

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

3² - 6 = 0

3 ² = 9, not 6. Correct answer is 3

4 + 5 + 7 - 3 x 2 = 26

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

10 ³ = 30

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