Order of Operations

Front

What is the Order of Operations in mathematics?

Back

The Order of Operations is a set of rules that determines the sequence in which operations should be performed in a mathematical expression. The common acronym used to remember the order is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What operation should be performed first in the expression (12 + 10) ÷ 10 x 14 - 6?

Back

Addition should be performed first, according to the Order of Operations.

Why is it important to follow the Order of Operations?

Back

Following the Order of Operations is important to ensure that mathematical expressions are evaluated consistently and correctly, leading to the same result regardless of who performs the calculation.

What does the acronym PEMDAS stand for?

Back

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

Front

In the expression 7 + 3 × 2, which operation is performed first?

Back

Multiplication is performed first, resulting in 7 + 6 = 13.

How do you handle operations of the same rank, such as multiplication and division?

Back

When operations of the same rank occur, such as multiplication and division, they are performed from left to right.
