What is the Order of Operations?

Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression.

Front

What does PEMDAS stand for?

Back

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

Front

Solve: 5 + 2 x 3

Back

11 (First multiply 2 x 3 = 6, then add 5)

Front

Solve: (4 + 6) ÷ 2

Back

5 (First add 4 + 6 = 10, then divide by 2)

Front

What operation do you perform first in the expression 8 + 2 x 5?

Back

Multiplication (2 x 5 = 10, then add 8)

Front

Solve: 12 - (3 + 1) x 2

Back

8 (First add 3 + 1 = 4, then multiply by 2 = 8, finally subtract from 12)

Front

What is the result of 9 ÷ 3 + 2?

Back

5 (First divide 9 ÷ 3 = 3, then add 2)

Front

Which operation is performed last in the expression 7 + 2 x (3 - 1)?

Back

Addition (First solve inside the parentheses, then multiplication, and finally addition)

Front

Solve: 6 x (2 + 4) - 3

Back

39 (First add 2 + 4 = 6, then multiply by 6 = 36, finally subtract 3)

Front

What is the value of 10 - 2 x 3 + 1?

Back

5 (First multiply 2 x 3 = 6, then subtract from 10 = 4, finally add 1)
