Alternatively:

x^2 - x = 20
x(x-1) = 20

What number times one less than itself equals 20?

>you can't multiply any matrix by a 1x1 matrix

Sure you can:

A [a] = aA

"I think it's interesting the two drugs that are legal, alcohol and cigarettes, two drugs that do absolutely nothing for you at all, are legal, and the drugs that might open your mind up to realize how badly you're being fucked every day of your life? Those drugs are against the law. He-heh, coincidence? See, I'm glad mushrooms are against the law, 'cause I took 'em one time, and you know what happened to me? I laid in a field of green grass for four hours going, "My God! I love everything." Yeah, Now, if that isn't a hazard to our country... how are we gonna justify arms dealing if we know we're all one?!"

Whats an example of a left-distributive operation (with regards to another) that is not right-distributive?

matrix multiplication

With regards to addition you mean? Thats both left and right distributive

an even more fun example is this, a simple projection operator onto the vector x,

[eqn]P=\frac{xx^\top}{x^\top x}[/eqn]

Go ahead and check that it satisfies
[eqn]P^2=P[/eqn]

Consider maps from R to R. Let the two operations be * = pullback or function composition and × = usual multiplication.

My school checks off most of that list.
