# Why is subtracting a negative number a positive number?

## Answer

It is a double negative, subtracting is essentially adding a negative, therefore subtracting would be a negative negative number, which would be a positive, my mom helped me remember it by thinking if a bad thing happened to a bad person, it would be good, if a good thing happened to a good person it would be good, if a bad thing happened to a good person it would be bad, ect.

### If your positive and negative number are the same does it become a negative number or positive number?

It depends on what you are doing to the two identical numbers.
If you are multiplying them, it becomes a negative. If you are
dividing them, it becomes a negative. If you are adding them, it
will always be zero (e.g., 2+ -2 = 0, etc.). There are two ways to
subtract. If you are subtracting a positive from a negative, the
number remains negative. If you are subtracting a negative from a
positive, or a negative from a negative, the negative becomes a
positive and you just add from there.

### What will be the difference when subtracting two integers with different signs?

Subtracting:
Positive - Negative = Positive
Negative - Positive = Negative
No that is not the way it goes. It is positive+negetive=either
counting on which integer is bigger
negative+negative=positive
positive+positive=positive
positive x negetive=negative
negative x postitve= negative
negative/positive=negative
positive/negative=negetive
thanks
The top is right though because subtracting a negative is like
adding so you could never get a negative and subtracting from a
positive from negative will always be a negative. The question was
for integers with different signs so you don't need to do "positive
+ positive"

### Why multiplication of negative numbers equals positive?

When you multiply any number by a negative number you reverse
its sign. So positive numbers become negative, and negative numbers
become positive. That is the meaning of negative multiplication; it
is reversal. This is similar to the way that adding a negative
number has the same effect as subtracting a positive number.
Negative is the opposite of positive.
