Question

Santa owes $63 on 1 bill & $54 on another. Express Santa's total debt as a negative number.

Answer 1

As the problem says that Santa owes $63 and $54, we have to add those numbers. However, as it is a debt then those numbers are negative:

`(-63)+(-54)=`

Simplifying:

`=-63-54`

As both numbers have the same sign, then we can add them:

`=-117`

Answer: -$117
