Find B-CF
B=%28matrix%282%2C2%2C2%2C8%2C.6%2C3%29%29
C=%28matrix%282%2C3%2C12%2C0%2C1.5%2C1%2C-6%2C7%29%29
F=%28matrix%283%2C2%2C-2%2C0%2C0%2C8%2C2%2C1%29%29
---------------------------------------

We do the multiplication first:



Now we do the subtraction:
B-CF=+%28matrix%282%2C2%2C2-%28-21%29%2C8-1.5%2C.6-12%2C3-%28-41%29%29%29

B-CF=+%28matrix%282%2C2%2C2%2B21%2C6.5%2C-11.4%2C3%2B41%29%29
B-CF=+%28matrix%282%2C2%2C23%2C6.5%2C-11.4%2C44%29%29
