Question

evaluate the expression.
30 + (21 ÷ 3) - (5 + 3)

Explanation:

Step1: Solve parentheses

First, calculate the expressions inside the parentheses. For \(21\div3\), we have \(21\div3 = 7\). For \(5 + 3\), we get \(5+3=8\). Now the expression becomes \(30 + 7-8\).

Step2: Perform addition and subtraction

Next, perform the addition first: \(30+7 = 37\). Then subtract 8 from 37: \(37 - 8=29\).

Answer:

\(29\)
