Find each sum or difference.

12-34

Short Answer

Expert verified

The difference of numbers is 鈥� 22.

Step by step solution

01

Step 1. Rewrite as a sum.

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

02

Step 2. Determine to add or subtract.

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

03

Step 3. Determine the sign.

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

We can write 12+(鈥�34)=鈥�(|鈥�34|鈥�|12|)

04

Step 4. Simplify.

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

So, 鈥�(|鈥�34|鈥�|12|)=鈥�(34鈥�12)=鈥�22
