Chapter 1: Problem 65

On a number line, what number is 4 units to the right of $6 ?$

Short Answer

Expert verified

Step by step solution

Identify the starting point

Determine the starting point on the number line, which in this case is 6.

Understand the direction

To move to the right on a number line means to add units. In this problem, you need to move 4 units to the right of 6.

Perform the calculation

Add 4 to the starting point 6. This can be represented as: \[ 6 + 4 \ = 10 \]

Key Concepts

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

Addition

Addition is a fundamental mathematical operation. It combines two or more numbers to get a total sum. When we talk about moving along a number line, addition helps us find new positions. For example, in the given exercise, we start at the number 6. By adding 4 to this number, we can find our new position.
The mathematical representation would be:

Starting point: 6
Units to move to the right: 4
Perform the calculation: 6 + 4 = 10

Moving Right

On a number line, moving to the right means we are increasing the value of our number. It's like walking forward. When we move right, we are essentially adding positive numbers. In the problem provided, we moved 4 units to the right from the starting point, which is 6.

Each step to the right increases the value by 1. So starting from 6 and moving 4 steps, it looks like this:

Step 1: Move from 6 to 7
Step 2: Move from 7 to 8
Step 3: Move from 8 to 9
Step 4: Move from 9 to 10

This is how we use moving to the right to solve the problem and arrive at the number 10.

Finding Positions on Number Line

Understanding how to find positions on a number line is crucial. A number line is a visual tool that represents numbers in sequence from left to right. Numbers increase as you move right and decrease as you move left.

Here's a simple way to find a position on a number line:

Start at the given number. In our case, start at 6.
Determine the direction. For this exercise, it's to the right since we're adding a positive number (4).
Count the number of units to move. Move 4 units to the right.
Land on the new position. After moving 4 units to the right of 6, we arrive at 10.

This method helps you accurately find and visualize any position on a number line.
