# Question

Can I move the variables around since we're dealing with addition and subtraction?

**Answer**

You can always change the *order* of the terms in an expression as long as you keep the sign:

Let's look at:

*a* - *b* + 3*c* - 2*d* - *e*

I could rearrange this to:

-2*d* - *b* + 3*c* + *a* - *e* or:

-*e* - *b* - 2*d* + a + 3*c* or:

3*c* + *a* - *e* - *b* - 2*d* or many more ways. Just remember the sign "-" or "+" in front of every term should be the same.
