Order of Operations

Front

What is the Order of Operations in mathematics?

Back

The Order of Operations is a set of rules that dictates the sequence in which calculations are 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).

Front

What operation should be performed first in the expression: 10 - 4 ÷ 1 x 5?

Back

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

Front

Calculate the result of the expression: 9 + 9 ÷ 9 + 9.

Back

The result is 19.

Front

What is the result of the expression: 2 + (9² - 4)?

Back

The result is 79.

Front

In the expression 4 + 9 + 8 ÷ 4, which operation is performed first?

Back

Division is performed first, resulting in 4 + 9 + 2.

Front

What do you do first in the expression: 12 ÷ 3 x 4?

Back

You perform the division first: 12 ÷ 3.

Front

What does PEMDAS stand for?

Back

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

Front

Why is it important to follow the Order of Operations?

Back

Following the Order of Operations is crucial to ensure that mathematical expressions are evaluated correctly and consistently.

Front

What is the result of the expression: 5 + 2 x 3?

Back

The result is 11, because multiplication is performed before addition.

Front

How do you handle operations of the same rank in the Order of Operations?

Back

When operations of the same rank (like multiplication and division) appear, you perform them from left to right.
