Homework: Orders of Operations Practice

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 calculations are performed. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

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

Back

Parentheses are symbols used to group numbers and operations together. Calculations inside parentheses should be performed first.

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

Back

Exponents indicate how many times a number (the base) is multiplied by itself. For example, 2^3 means 2 x 2 x 2.

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

Back

Multiplication is a mathematical operation where a number is added to itself a certain number of times. It is performed before addition and subtraction in the order of operations.

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

Back

Division is the process of determining how many times one number is contained within another. It is performed before addition and subtraction.
