Find each sum or difference.

41+-56

Short Answer

Expert verified

The sum of the numbers is 鈥�15.

Step by step solution

01

Step 1. Determine to add or subtract.

Since 41 and 鈥� 56 are of opposite signs. So we will subtract them.

02

Step 2. Determine the sign.

Subtract the absolute values. Since, |鈥�56| is greater than |41|, so the result will be negative.

We can write41+(鈥�56)=鈥�(|鈥�56|鈥�|41|)

03

Step 3. Simplify.

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

So,-(|-56|-|41|)=-(56鈥�41)=-15
