Is there a way to simplify x-x-x?

[eNathan]

Is there a way to simply x-x-x? I know that x+x+x can by simplifed as 3x, but what about subtraction? One would think that if multiplication is just a simplification of addition, then indeed, division is just a simplification of subtraction. I need to know this for an equation I have to make for a software like always

Any help? x-x-x

Sure, what does x - x equal? Also, x - x = x + (-x). And notice that -x = (-1)*x.

It seems that I can just use exponents for this, so let me ask this insead.

I want to subtract m from x n amount of times. Let's say n = 5, m = 10, and x = 26.

x - 26-26-26-26-26

Isnt their a simpler way?

 

[Icebreaker]

x - 26-26-26-26-26 = x - 5*26

x-x-x = -x

Ok, I got it all down.

m -x-x-x-x = m-(4x)

Thx a lot! :}
