Order of Operations

Front

What is the Order of Operations?

Back

The Order of Operations is a set of rules that tells you the correct sequence to evaluate a mathematical expression. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Often remembered by the acronym PEMDAS.

Front

What do you do first in the expression 12 ÷ 3 x 4?

Back

You perform the division first: 12 ÷ 3 = 4.

Front

True or False: Addition ALWAYS comes before subtraction in the Order of Operations.

Back

False. Addition and subtraction are performed from left to right, depending on which comes first.

Front

Solve the expression (12 + 51) - 4^2.

Back

47. First, calculate inside the parentheses: 12 + 51 = 63. Then calculate the exponent: 4^2 = 16. Finally, subtract: 63 - 16 = 47.

Front

What is the result of (7 + 41) ÷ 2 – 15?

Back

9. First, calculate inside the parentheses: 7 + 41 = 48. Then divide: 48 ÷ 2 = 24. Finally, subtract: 24 - 15 = 9.

Front

What is the result of 5 x (6 - 3)?

Back

15. First, calculate inside the parentheses: 6 - 3 = 3. Then multiply: 5 x 3 = 15.

Front

What does PEMDAS stand for?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). It is a mnemonic to remember the Order of Operations.

Front

In the expression 8 + 2 x 5, what operation do you perform first?

Back

You perform multiplication first: 2 x 5 = 10.

Front

What is the value of 3 + 4 x 2?

Back

11. First, multiply: 4 x 2 = 8. Then add: 3 + 8 = 11.

Front

What is the result of 10 - 2 + 3?

Back

11. You perform the operations from left to right: 10 - 2 = 8, then 8 + 3 = 11.
