You can put this solution on YOUR website! The algebraic rule is that if you multiply two numbers together and they both have the same sign,
the answer is positive.
.
If you multiply two numbers together and they have different signs (one number is positive and
the other is negative) the answer is negative.
.
In this problem, both numbers have the same sign ... both are negative. Therefore, the answer
must be positive. Multiply the 5 times the ll and get 55 and make it a positive answer or +55.

Hope this helps you to understand algebraic multiplication a little better.
