Order of Operations with DECIMALS!

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 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 important to ensure that everyone calculates expressions in the same way, leading to consistent and correct results.

Front

What is the first step in the Order of Operations?

Back

The first step is to solve expressions inside Parentheses.

Front

What do you do after solving Parentheses in an expression?

Back

After solving Parentheses, the next step is to evaluate Exponents.

Front

How do you handle Multiplication and Division in the Order of Operations?

Back

Multiplication and Division are performed from left to right as they appear in the expression.

Front

How do you handle Addition and Subtraction in the Order of Operations?

Back

Addition and Subtraction are also performed from left to right as they appear in the expression.

Calculate: 5 - 3 + 2

Back

The correct order is to subtract first: 5 - 3 = 2, then add: 2 + 2 = 4.

Front

Calculate: (8 + 56 - 24.2) ÷ 2

Back

First, solve inside the parentheses: 8 + 56 - 24.2 = 39.8, then divide: 39.8 ÷ 2 = 19.9.

Front

Calculate: 3(5⋅9.2 + 4) - 85

Back

First, solve inside the parentheses: 5⋅9.2 + 4 = 46, then multiply: 3 × 46 = 138, and finally subtract: 138 - 85 = 53.
