spoonitnow's Mathematics of EV Thread

[Savy]

Read the Algebra section, it explains everything very well, basically boils down to this

A(B - C) = AB - AC

And

A(B + C) = AB + AC


Where AB = A*B

Question (if you know the answer it is very simple, not a trick question at all)

What is AC?

(If you can't answer that then you need to read the section on variables again)

Spoiler: Show

AC = A * C

This means that when we write EF we actually mean E * F. So if we wanted to write E * EF this would be E * E * F.

AC = A*C .when two variables are beside each other like "AC" I must multiply the two together,
unless told otherwise with a + - / etc sign.
(I'm just trying to show you I understand this. Am I correct?).

I've re-read the algebra section and I must be missing something because I now don't understand the red
part of the formula below (is it called a formula ? ).

F + E(1-F) + (1-F)(1-E)

= 1 - E - F + EF . Where did the plus sign come from.

I'm going to take a guess here and say
I must add the EF on the end because I took away EF from E in the blue part of the formula? But I thought this rule only applied to equations.
