We've now learned to add and subtract matrices... how to multiply a matrix by a scalar... and how to multiply two matrices...
So, what about division?
Well, there isn't a division process for matrices. BUT, there IS a way to get around this little problem. We can use something we already know about: multiplication.
Here's the scoop:
Say you need to solve this guy...
What do we do? We divide both sides by 3:
Let's take a closer look at what's going on here:
Instead of saying that we are dividing by 3, how about saying that we are multiplying by :
The result is the same, but we used multiplication instead of division.
