Order of Operations Review

Front

What is the order of operations?

Back

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

Front

What does 'P' in PEMDAS stand for?

Back

'P' stands for Parentheses. Calculations inside parentheses should be done first.

Front

What does 'E' in PEMDAS stand for?

Back

'E' stands for Exponents. After parentheses, calculations involving exponents should be performed.

Front

What does 'MD' in PEMDAS represent?

Back

'MD' stands for Multiplication and Division. These operations are performed from left to right.

Front

What does 'AS' in PEMDAS represent?

Back

'AS' stands for Addition and Subtraction. These operations are also performed from left to right.

Front

Solve: 3 + 5 × 2

Back

13 (First, multiply 5 × 2 = 10, then add 3.)

Front

Solve: (4 + 6) × 2

Back

20 (First, calculate inside the parentheses: 4 + 6 = 10, then multiply by 2.)

Front

Solve: 8 - 3 + 2

Back

7 (Perform addition and subtraction from left to right: 8 - 3 = 5, then 5 + 2 = 7.)

Front

Solve: 2 × (3 + 4) - 5

Back

9 (First, calculate inside the parentheses: 3 + 4 = 7, then 2 × 7 = 14, and finally 14 - 5 = 9.)

Front

Solve: 6 + 2 × 3 - 4

Back

8 (First, multiply 2 × 3 = 6, then add and subtract from left to right: 6 + 6 - 4 = 8.)
