But I was thinking about substituting the variables for some numbers.

So why did it only cancel out the 4 and not the 2. was it to only find half of from only one part (or one number).

it is half base times height OR half height times base half height = 4z/2 = 2z

it works the same as \[ \frac{1}{2} \cdot 4 \cdot 8 \] you can group it like this \[ \left(\frac{1}{2} \cdot 4 \right) \cdot 8\] only the 4 *1/2 is simplified to 2 and you get 2*8 or 16 if 8 were something complicated like (x+2y) it still be \[ \left(\frac{1}{2} \cdot 4 \right) \cdot (x+2y)\]

we know that 2+1 = 3 nd if we find out (2+1)/2 then we can't cancel out 2 :) if u cancell it out then ur left with 1 but we know that 2+1 = 3 nd 3/2 is not 1. so u can't divide like that
