Answer: -9
Step-by-step explanation: When you're asked to multiply positives and negatives together, the rules are simple.
<em><u>A positive times a positive is a positive.</u></em>
<em><u>A positive times a negative is a negative.</u></em>
<em><u>A negative times a positive is a negative.</u></em>
<em><u>A negative times a negative times a negative is a positive.</u></em>
So for the problem you see here, we will use rule 2 which I have highlighted in bold above which states that a positive times a negative is a negative.
So (+3)(-3) = -9
the answer is (A) you cant have 11 it should be 1.1 x 10^22
