# Subtracting vectors

Subtracting - Reverse

Reverse the direction of the vector you want to subtract

**Example 1**

Subtract vector `a` from vector `b`

Place the first vector `a` and add on the reverse of vector `b`

The result is a new vector `c`

**NOTE:**

It doesn't matter in which order you subtract vectors or add vectors. Therefore:

`a-b=-b+a`

But try `-b+a` and see for yourself.

`a-b=c` and `-b+a=c`

Another way of showing `a-b=-b+a` is as follows:

**Example 2**

`a-b=-b+a`

**Example 3**

Vector `r=a-b+c+d`

Also

Vector `r=c+a-b+d`

You can add vectors and reversed vectors in any order.
