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. It is often remembered by the acronym PEMDAS: 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: P - Parentheses, E - Exponents, MD - Multiplication and Division (from left to right), AS - Addition and Subtraction (from left to right).

Front

What is the first step in solving 3 + 4 * 6 - 4?

Back

The first step is multiplication: 4 * 6 = 24.

Front

What is the result of 5 - 3 + 2?

Back

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

Front

What is the correct way to handle addition and subtraction?

Back

Addition and subtraction should be performed from left to right.

Front

What is the value of 2(1.5 + 2.5)?

Back

First, calculate inside the parentheses: 1.5 + 2.5 = 4. Then multiply: 2 * 4 = 8.

Front

What is the value of 0.2(18) + 24?

Back

First, calculate 0.2 * 18 = 3.6. Then add 24: 3.6 + 24 = 27.6.

Front

What is the importance of parentheses in order of operations?

Back

Parentheses indicate which calculations should be performed first, overriding the normal order of operations.

Front

What happens if you ignore the order of operations?

Back

Ignoring the order of operations can lead to incorrect answers in mathematical expressions.

Front

What is an exponent?

Back

An exponent indicates how many times a number (the base) is multiplied by itself. For example, 2^3 means 2 * 2 * 2 = 8.
