There are no E xponents.
This expression has multiplication and division only. M ultiplication comes a step before S ubtraction, so first we multiply 3 x 2, and then subtract the sum from 6, leaving 0.
Another common way to remember the order is the mnemonic. What happens if a problem has exponents or square roots in it?
Two examples are shown. Parentheses are a grouping symbol, and numbers inside them should be computed first. Addition and Subtraction are also done in the same step. P arentheses first: In other languages Add links. The second set indicates multiplication.

The order of operations requires that all multiplication and division be performed first, going from left to right in the expression. If we had blindly done the addition first, we would have got the answer 2, which is wrong!
Parentheses first: M ultiplication before A ddition: The exponent of 2 tells you to multiply the number by itself, not by 2. The first set of parentheses is a grouping symbol.
That is, begin simplifying the innermost grouping symbols first. D 156 Incorrect. After multiplication and division has been completed, add or subtract in order from left to right.
