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. I should have solved 5 x 2 as my first equation.  

Fix my Mistake

9 - 3 x 2=12

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

5 + 7 x 3= 36

7 x 3 is the first equation. 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.
