Adding/Subtracting

When adding and subtracting two numbers with different signs, you always follow this rule:

If the negative is before the positive number, then switch them

-5+4 to 4-5

4-5 is -1.

You could also switch the signs from -5+4 to 5-4

you end up with one, but the answer will have the same sign as the larger number.

So you still end up with -1.

If the positive number is before the negative, Ex:

6+-2

and the larger number is the positive number, you follow the "Keep it. Change it. Change it." Rule.

Keep the 6.

Change the + to -

Change the -2 to a +2, also written as 2

So, 6-2.

answer would be 4.
