Order of Operations Flashcard

Front

What is the order of operations?

Back

Parentheses, Exponents, Multiply or Divide, Add or Subtract (PEMDAS)

Front

What should you do first in the expression 5 - 3 + 2?

Back

You should subtract first: 5 - 3 = 2, then add 2 to get 4.

Front

Calculate: 15 + 7 × 2 – 11 + 35

Back

53 (Follow the order of operations: 7 × 2 = 14, then 15 + 14 - 11 + 35 = 53)

Front

Calculate: (7 + 41) ÷ 2 – 15

Back

9 (First, calculate inside the parentheses: 7 + 41 = 48, then 48 ÷ 2 = 24, and finally 24 - 15 = 9)

Front

In the expression (12 + 10) ÷ 10 x 14 - 6, which operation do you do first?

Back

Addition (12 + 10 = 22, then continue with the order of operations)

Front

What does PEMDAS stand for?

Back

Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)

Front

What is the result of 8 + (3 × 4)?

Back

20 (First, calculate inside the parentheses: 3 × 4 = 12, then 8 + 12 = 20)

Front

What is the result of 20 - 4 ÷ 2 + 3?

Back

19 (First, divide: 4 ÷ 2 = 2, then 20 - 2 + 3 = 21)

Front

What is the result of 6 × (2 + 3) - 4?

Back

26 (First, calculate inside the parentheses: 2 + 3 = 5, then 6 × 5 - 4 = 30 - 4 = 26)

Front

What is the error in the expression 5 - 3 + 2 = 0?

Back

The error is that addition was done first instead of subtraction.
