Best Answer

The order of operation is:

1 Brackets

2 Exponents (power and roots)

3 Multiplication and Division

4 Addition and Subtraction

Consider: 3 + 4 x 2 = 11

The 4 x 2 was done first, then the answer 8 + 3 = 11

Using the order of operations:

(3 + 4) x 2 = 14

The (3+4) was done first, then the answer 7 x 2 was done last, giving 14 as the correct answer.
