Chapter 1: Problem 22

Find each sum without the use of a number line. $$-7+3$$

Short Answer

Expert verified
The sum of -7 and 3 is -4.

Step by step solution

01

Identify the Numbers

The numbers given are -7 and +3.
02

Adding Positive and Negative Numbers

When adding a positive number to a negative number, the result gets closer to zero. The magnitude takes precedence, so -7 being larger in magnitude than +3 would push the sum into the negative range.
03

Perform the Addition

So perform the operation -7 + 3. Subtracting 3 from 7 gives us \( -4 \). Thus, \( -7 + 3 = -4 \).
