Adding vectors

Adding - Just ADD

JUST position the first vector &
ADD the second vector 

 

Example 1

Add vector `a`  to vector `b`

Take 2 vectors one with a height of 3 and one with the height of 2 

Just join the second vector up with the first vectors destination end

Place the first vector `a`  and add on the second vector.

The result is a new vector `c`

Draw a straight line from the start of the first vector to the end of the second, this is now the new vector.

 

NOTE:

It doesn't matter in which order you add the vectors.

 

Try adding `b+a`

You can add vectors in any order making the new vector the same

`a+b=c`  and `b+a=c`

ANOTHER way of showing that `a+b=b+a`  is as follows:

 

Example 2

Put vector a and b in parallel with each other then join to form a square 

`a+b=b+a`

 Adding the vectors twice to make a new shape, the new resulting vector should still be the same

Example 3

You can add a vector to complete a shape, but by adding the other vectors first 

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

 

Also

You can add the previous vectors to each other in a different order and the resulting vector should be the same 

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

 

And also

Adding vectors in any order makes the resulting vector the same 

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

You can ADD IN ANY ORDER.
