S1 Order of Operations Final

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).

Front

What operation should be performed first in the expression: 12 - 4 and 4 x 2?

Back

4 x 2 (Multiplication is performed before subtraction).

Front

What operation should be completed first in the expression: 4 - 12, 12 ÷ 6, 6 x 5, 5 + 11?

Back

12 ÷ 6 (Division is performed before subtraction, multiplication, and addition).

Front

Evaluate the expression: 2 + 3 x 4 - 5.

Back

9 (First, multiply 3 x 4 = 12, then 2 + 12 - 5 = 9).

Front

Which operation should be completed first in the expression: 2 + 7, 7 - 1, 1 ÷ 2², 2²?

Back

2² (Exponents are calculated before addition and subtraction).

Front

Evaluate the expression: 3 + 5 x (2 - 1).

Back

8 (First, calculate inside the parentheses: 2 - 1 = 1, then 5 x 1 = 5, finally 3 + 5 = 8).

Front

What is the result of the expression: 10 - 2 x 3 + 4?

Back

8 (First, multiply 2 x 3 = 6, then 10 - 6 + 4 = 8).

Front

Evaluate the expression: (3 + 5) x 2 - 4.

Back

12 (First, calculate inside the parentheses: 3 + 5 = 8, then 8 x 2 - 4 = 12).

Front

What is the value of the expression: 5 + 2² x 3?

Back

17 (First, calculate the exponent: 2² = 4, then 4 x 3 = 12, finally 5 + 12 = 17).

Front

Which operation should be performed first in the expression: 8 ÷ 2 + 3 x 4?

Back

8 ÷ 2 (Division is performed before addition and multiplication).
