Chapter 1: Problem 2

Find each sum using a number line. $$7+(-2)$$

Short Answer

Expert verified
The sum of \(7 + (-2)\) is 5.

Step by step solution

01

Start With the Positive Number on the Number Line

Place a point at the number 7 on the number line, as this is the positive number in the equation \(7 + (-2)\). This is the starting point.
02

Move to the Left for the Negative Number

The number -2 is a negative integer. On the number line, positive integers are to the right while negative integers are to the left. Therefore, from the starting point 7, move 2 places to the left.
03

Identify the Resultant Position on the Number Line

After moving 2 places to the left from the point 7, the resultant point on the number line is 5. This represents the sum of \(7 + (-2)\).
