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.
Negative two times three is negative six.

Positive times negative = negative -18
Negative times negative is positive. Negative 2 times negative 2 equals positive 4.
List numbers that multiply to make 28 and find their sums. Since negative times a negative is positive, list the negatives. -1, -28 = -29 -2, -14 = -15 -4, -7 = -11 Aha! -4 and -7 multiply to make 28 and add to -11; therefore, -4 and -7 are the two numbers.
Seven minus negative two times negative 4 is equal to -1
Negative four

a negative times positive is negative 2 times negative 10 = negative 20
