TUITION KIDS
what is (1+4)(5) = ?
i dunno!
okie, the brackets means times okie... so what is (1+4)(5)=?
how do u times 1 plus 4 times 5? doesn't make sense!!
okie i rewrite for u k, (1+4) x 5. what is it? is the same as 5 + 20 isnt it?
Ya.
so what if i (x + 2)(3), is the same as 3x + 6 right?
NO.
why not?
ITS NOT THE SAME!
okie, never mind. then show me ur way then.
x + 6
so where's the 3x? u see the (1+4)x5 question. u must apply ur order. 5x1 then + 5x4.
so same. u must 3 times x then plus 3x6. understand?
no.
fine. how about (x) times 3?
3x.
what's 3 times 2?
6
u plus them together what do u get?
3x + 6.
so isn't 3x + 3x2 the same as (x+2) times 3?
ya.
understand now?
ya okie.
so what's (x+2) x 3?
x + 6.
It's wrong! I thought u know how to do already?
Huh? I didn't understand a single thing u said.
ARGH. that's my tuition kid. u either love her or beg her to stab u.
