**3(-4)(5)(-2) = 120 The answer is a positive number. There are two
ways of doing this: 3(-4) = -12 and -12(5) = -60 and a -60(-2) =
120 You can do this problem by multiply two numbers together
at a time and use the previous rules. OR In a multiplication
problem count the number of negative signs in the total problem. If the total
number is even the answer is positive and if the number is odd the answer will
be negative. For example -4(3)(-6)(-1) = -72 There are 3
negative signs in the problem so the answer is negative. If the problem
was -4(-3)(-6)(-1) the answer would be a positive 72 because there are 4
negative signs in the problem.**
