Order of Operations with Rational Numbers

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).

What is the first step in solving 3 + 4 x 6 - 4?

Back

Multiplication (4 x 6) should be done first.

Front

What is a rational number?

Back

A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

Front

What is the difference between multiplication and addition in the context of order of operations?

Back

In the order of operations, multiplication is performed before addition. This means that in an expression, you should calculate multiplication first before adding any numbers.

Front

What is the result of 5 + 3 x 2?

Back

11 (because 3 x 2 is calculated first, resulting in 6, then 5 + 6 = 11).
