Chapter 1: Problem 40

Subtract. $$ 0-8 $$

Short Answer

Expert verified

-8

Step by step solution

Understand the Operation

The task is to subtract 8 from 0. Subtraction involves taking away a certain amount from another number.

Set Up the Equation

Write the expression clearly: \[ 0 - 8 \]

Apply the Subtraction Rule

When subtracting a larger number from a smaller number, the result is negative. Imagine borrowing 8 from someone but you have 0 to start with.

Calculate the Result

Since we are subtracting a larger number (8) from a smaller number (0), the result is negative: \[ 0 - 8 = -8 \]

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Subtraction Rules

Subtraction is one of the basic arithmetic operations. It involves taking one number away from another. Here are some key rules for subtraction:

Subtraction is not commutative, meaning that changing the order of the numbers changes the result. For example, 8 - 3 is not the same as 3 - 8.
When subtracting a larger number from a smaller number, the result will be negative. For instance, 3 - 5 results in -2.
Subtracting a number from itself always results in zero. For example, 7 - 7 = 0.

Understanding these rules will help you tackle subtraction problems more effectively.

Negative Numbers

Negative numbers are numbers less than zero. They are written with a minus sign (-) in front of them, like -8 or -3.

Negative numbers are used to represent values below zero, like temperatures below freezing or debt.
When you subtract a positive number from zero, you move to the negative side of the number line. For example, 0 - 8 = -8.
Remember, the more you subtract, the further you go into negative value. Subtracting 5 from -3 (-3 - 5) results in -8.

Working with negative numbers may seem tricky at first, but with practice it becomes much easier.

Basic Arithmetic

Basic arithmetic is the foundation of all mathematics and includes addition, subtraction, multiplication, and division. Here are some important concepts:

Addition is combining two numbers to get a sum, like 3 + 5 = 8.
Subtraction is taking one number away from another, such as 8 - 3 = 5.
Multiplication is repeated addition, for example, 3 x 4 is the same as adding 3 four times (3 + 3 + 3 + 3 = 12).
Division is splitting a number into equal parts. For instance, 12 梅 4 = 3.

These basic operations are tools you'll use all the time in mathematics, so it's important to get comfortable with each one.
