Order of Operations & Integers Review

Front

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 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 is an Integer?

Back

An integer is a whole number that can be positive, negative, or zero. Examples include -3, 0, and 5.

How do you add integers with different signs?

Back

When adding integers with different signs, subtract the smaller absolute value from the larger absolute value and keep the sign of the integer with the larger absolute value.

What is the result of -12 + 9?

Back

The result is -3.

What is the first step in solving the expression 14 + (22 - 2)?

Back

The first step is to solve the expression inside the parentheses: (22 - 2) = 20.

What is the result of 20 x 2 - (10 - 4)?

Back

The result is 34.

What does 'Multiplication' mean in the context of Order of Operations?

Back

Multiplication is one of the basic arithmetic operations that combines groups of equal sizes. It is performed after parentheses and exponents in the Order of Operations.

What is the result of 5 x (7 - 2) + (8 + 1)?

Back

The result is 34.
