Front

What is the first step in solving the expression: 5 + 3 × 2?

Back

Multiplication: 3 × 2 = 6, then add 5.

Front

Evaluate: 8 - 2 + 4 × 3

Back

First, perform multiplication: 4 × 3 = 12, then 8 - 2 + 12 = 18.

Front

What is the result of: (6 + 2) × 3?

Back

First, solve inside the parentheses: 6 + 2 = 8, then multiply: 8 × 3 = 24.

Front

Solve: 10 - (2 + 3) × 2

Back

First, solve inside the parentheses: 2 + 3 = 5, then multiply: 5 × 2 = 10, finally: 10 - 10 = 0.

Front

What is the importance of parentheses in an expression?

Back

Parentheses indicate which operations should be performed first.

Front

Evaluate: 12 ÷ 4 + 5 × 2

Back

First, perform division: 12 ÷ 4 = 3, then multiplication: 5 × 2 = 10, finally: 3 + 10 = 13.

Front

What is the result of: 3 + 6 ÷ 2 - 1?

Back

First, perform division: 6 ÷ 2 = 3, then: 3 + 3 - 1 = 5.

Front

What is the result of: 5 × (2 + 3) - 4?

Back

First, solve inside the parentheses: 2 + 3 = 5, then multiply: 5 × 5 = 25, finally: 25 - 4 = 21.
