Negetive 28 and 1
180 * 28 = 5,040
In order to multiply two numbers together when one or more of them is negative, you start by multiplying them normally. In this case 4x7 = 28. The next step is to assess whether or not the answer is a negative or positive. If the two numbers being multiplied were the same (both negative or both positive) then the answer is positive. Otherwise, it is negative. In this case, we had -4 and -7 which are both negative, so the answer is positive 28. Thus the question can be rewritten as 2x28. This comes out as 56. Therefore 2 times negative 4 times negative 7 is 56.
