If you have a list of numbers, some positive some negative, and want to multiply them together, first just multiply them without regard to the sign. Then if the number of negatives is odd put a negative sign in front of the answer while if it is even don't do anything.
So, for example,
(-3)*(-4)*(2)*(-5)
then 3*4*2*5 = 120
there are three negative numbers (odd) so the answer is -120
or
(3)*(-4)*(2)*(-5)
again 3*4*2*5 = 120
there are two negative numbers (even) so do nothing: the answer is 120

Can a multiple of a number be of lesser value?
Yes, if either the number, or its multiple, are negative, or, a fraction. Of course, not both can be negative!!!
How do you find a multiple?
A multiple of a number is something you get when you multiply that number by another. For instance, 5 x 2 = 10, so 10 is a MULTIPLE of 5 and a MULTIPLE of 2. If you're trying to find a multiple of a number, say, 3, multiply that number by another. It can be any number.
How do you multiple and divide positive and negative integers?
multiplying and dividing a negative number will "flip" the sign of the other number. So multiplying two negative numbers will produce a positive number. Multiplying one positive and one negative number will produce a negative. And of course two positive numbers yield a positive.
A number that is multiplied by another number to find the product?

How do you find out if a number is a multiple of 3?
you add up the digits, and if the sum is a multiple of 3, then the number is divisible by 3!
