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 is the acronym used to remember the Order of Operations?

Back

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

Front

What do you do first in the expression: 5 + (3 x 2)?

Back

Calculate the expression inside the parentheses first: 3 x 2 = 6, then add 5 + 6 = 11.

Front

What is the result of 10 - 4 ÷ 1 x 5?

Back

First, perform the division: 4 ÷ 1 = 4, then multiplication: 4 x 5 = 20, finally subtraction: 10 - 20 = -10.

Front

What is the value of 5 x (3.8 + 3.2) - 6?

Back

First, calculate inside the parentheses: 3.8 + 3.2 = 7, then multiply: 5 x 7 = 35, finally subtract: 35 - 6 = 29.

Front

What is the correct order of operations?

Back

Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Front

What is the value of (7 x 5) + (6 x 4)?

Back

First, calculate each multiplication: 7 x 5 = 35 and 6 x 4 = 24, then add: 35 + 24 = 59.

Front

In the expression 18 + (6 – 2) × 2, what do you calculate first?

Back

Calculate inside the parentheses first: 6 - 2 = 4, then multiply: 4 x 2 = 8, finally add: 18 + 8 = 26.

Front

What does 'parentheses' mean in the context of order of operations?

Back

Parentheses are symbols used to group parts of a mathematical expression, indicating that the operations inside should be performed first.

Front

What is the result of 8 + 2 x 5?

Back

First, perform the multiplication: 2 x 5 = 10, then add: 8 + 10 = 18.
