When you multiply a negative number by a positive number what happens explain?

Multiplication is an abbreviation of addition:
4 x 5 is the same as:
adding 4 together 5 times: 4 x 5 = 4 + 4 + 4 + 4 + 4 = 20; or
adding 5 together 4 times: 4 x 5 = 5 + 5 + 5 + 5 = 20
When multiplying a negative number by a positive number, it can be thought of adding the negative number to itself the positive number of times.
eg -4 x 5 = -4 + -4 + -4 + -4 + -4 = -20
eg -5 x 4 = -5 + -5 + -5 + -5 = -20
Adding a negative number is the same as subtracting the number (as a positive number):
eg 7 + -3 = 7 - 3 = 4
eg -7 + -3 = -7 - 3 = -10

∙ 9y agoThe result of a negative number multiplied by a positive number is a negative number.
It is probably easiest to understand it as follows:
Suppose that the two numbers A and B are both positive, so that (-B) is negative.
[B + (-B)] = 0
Now, anything multiplied by 0 is 0
so A*[B + (-B)] = 0.
Expanding this gives A*B + A*(-B) = 0.
This means that the second term A*(-B) is the additive inverse [opposite] of the first, A*B.
That is A*(-B) = -A*B

Why when you multiply and negative number and a positive number it always equals a negative number?
This happens because a negative number is dominant over a positive one, so the number will multiply just as if you were multiplying even numbers, but at the end, just put a negative symbol. Also, if you multiply two negatives, they cancel themselves out, and the answer just becomes positive, but that only goes when multiplying an even amount of negative numbers together. For all of these, do the equation the same way, but at the end you may have to just add or take away a negative or positive symbol.
