Chapter 1: Q5. (page 12)

Find each sum or difference.
$12 - 34$

Short Answer

Expert verified

The difference of numbers is – 22.

Step by step solution

Step 1. Rewrite as a sum.

To subtract 34, we will add its inverse. 12 + ( –34).

Step 2. Determine to add or subtract.

Since 12 and – 34 are of opposite signs. So we will subtract them.

Step 3. Determine the sign.

Subtract the absolute values. Since, |–34| is greater than |12|, so the result will be negative.

We can write $12 + (- 34) = - (| - 34 | - | 12 |)$

Step 4. Simplify.

We know that the absolute values of the non-zero numbers are always positive.

So, $- (| - 34 | - | 12 |) = - (34 - 12) = - 22$
