Question

which of the following shows the correct order to solve (5 + 2) × 3 - 4? add, multiply, subtract; multiply, add, subtract; subtract, add, multiply; multiply, subtract, add

Explanation:

Step1: Recall PEMDAS/BODMAS rule

The order of operations is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). For the expression \((5 + 2)\times3 - 4\), first, we solve the operation inside the parentheses.

Step2: Solve the operation in parentheses

Inside the parentheses, we have \(5+2\). So we perform the addition first: \(5 + 2=7\).

Step3: Perform the multiplication

After solving the parentheses, the expression becomes \(7\times3 - 4\). Now we perform the multiplication: \(7\times3 = 21\).

Step4: Perform the subtraction

After multiplication, the expression is \(21-4\). We perform the subtraction: \(21 - 4=17\). So the order of operations is add (inside parentheses), multiply, then subtract.

Answer:

A. Add, multiply, subtract
