Back

False, multiplication comes before addition.

Front

What is the value of: 4 × (3 + 2)?

Back

The value is 20, as you first solve the parentheses: 3 + 2 = 5, then multiply: 4 × 5 = 20.

Front

Solve: 10 - (2 + 3) × 2

Back

10 - (2 + 3) × 2 = 10 - 5 × 2 = 10 - 10 = 0.

Front

What is the error in this calculation: 5 + 2 × 3 - 1 = 5 + 6 - 1 = 10?

Back

The error is in the order of operations; it should be 5 + 6 - 1 = 10, which is correct.

Front

What is the result of: -3 + 4 × 2?

Back

The result is 5, as you perform multiplication first: 4 × 2 = 8, then add: -3 + 8 = 5.

Front

What does the term 'exponents' refer to in PEMDAS?

Back

Exponents refer to numbers raised to a power, indicating how many times to multiply the number by itself.
