Order of Operations

Front

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: 3 + 4 x 6 - 4

Back

19 (First, multiply 4 x 6 = 24, then 3 + 24 - 4 = 23).

Front

What is the first step in solving 15 + 7 × 2 – 11 + 35?

Back

Multiplication (7 x 2 = 14).

Front

Solve: 16 + [ 3 x (9-6)^2 ]

Back

43 (First, solve inside the parentheses: 9-6=3, then square it: 3^2=9, then multiply: 3x9=27, finally add: 16+27=43).

Front

What is the value of (4-2) x 9 + 7?

Back

25 (First, solve the parentheses: 4-2=2, then multiply: 2x9=18, finally add: 18+7=25).

Front

What is the second step in solving 3 x 48 / (15 - 3)?

Back

Subtraction (15 - 3 = 12).

Front

What is the result of 48 / 12?

Back

4.

Front

What is the difference between addition and multiplication in the Order of Operations?

Back

Multiplication is performed before addition according to the Order of Operations.

Front

What is an exponent?

Back

An exponent indicates how many times a number (the base) is multiplied by itself.
