What this skill is

Solving expressions with parentheses in the right sequence.

When it comes up: Fifth grade.

The mistake to watch for

Working strictly left to right and ignoring the parentheses — (3 + 4) × 2 answered as 11.

How to help

Have your child rewrite the expression with the parenthesis already solved before doing anything else. One line of extra writing removes the error.

Next: Expressions with variables in middle school.

A worked example

Solve 6 + 4 × 3. Multiply before you add: 4 × 3 = 12, then 6 + 12 = 18. If you added first you would get 30, which is wrong. Parentheses go first: (6 + 4) × 3 = 30.

Words to know

operation: A kind of math work: adding, subtracting, multiplying or dividing.
parentheses: The curved marks ( ) that show which part to work out first.
multiply: To add the same number again and again, in a faster way.
add: To put numbers together to find how many in all.
order: The way things are arranged, one after another.

Practice

Solve. Work inside the parentheses first.
