QM LT 13 Order of operations practice

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The acronym PEMDAS is often used: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What is the first step in solving the expression: -2 ⋅ (3 + 8 ÷ 4)²?

Back

Division (8 ÷ 4) is performed first.

Front

Which operation should be performed first in the expression: 6x7 + (9 - 3) + 2?

Back

The operation (9 - 3) should be performed first.

What does the term 'exponent' mean in mathematics?

Back

An exponent is a number that indicates how many times to multiply the base by itself. For example, in 2², 2 is the base and 2 is the exponent, meaning 2 × 2.

Front

What is the result of 8 ÷ 4 × 2?

Back

4 (Perform division and multiplication from left to right).

Front

What is the significance of parentheses in mathematical expressions?

Back

Parentheses indicate which operations should be performed first in an expression.

Front

Evaluate the expression: 5 + 2 × (3 + 1)

Back

13 (First calculate inside the parentheses, then multiplication, then addition).
