Q & A: Retardedness

[Eijolend]

Why is this so complicated?

I know Franklin is dead, but who is this Mr Frankln?

[Wildt4lon]

Wrong, Ekofox
14g-5gk-6xy mwahaha

Ok, that's not a simplification, that's a change of the expression. You get a different result if you evaluate that versus the original expression. Example: For g = 1, k = 2, x = 3, y = 4;
Original expression = -68
Your 'simplified' expression = 76
Order of operations is important.

Back on topic: That was supposed to be Ben Franklin...
What's the difference between saying, " I mean what I say" and' "I say what I mean?"


(Answering eijolend's question)
Because we're all mad here.

I do not approve of your logic.

FIRST EXPRESSION: 14*1-(5*1*2+6*3*4)=14-(10+72)=14-82=-68.
SECOND EXPRESSION: 14*1-5*2*1-6*3*4=14-10-72=-68.

I can math properly

[Wildt4lon]

I think some of your maths is a little rusty, ekofox

[EkoFox]

In your second expression you swapped an addition with a subtraction symbol.

I was solving as if you had only taken out the parentheses.

[Wildt4lon]

What's the answer to this question?


Well, 'I mean what I say' means that you mean what you say. And of course, 'I say what I mean' means that you say what you mean. so the first two words and the last two words swap around. That can't possibly be wrong because it's TRUE.

Ekofox, I swapped + for a - AND got rid of the brackets. Any clues there?

When do you multiply by -1?
If you're saying you multiplied the whole thing by -1, the it would have to be -1(14g - (5gk + 6xy)) = -14g - (-5gk - 6xy). But the point is that is the expression in its simplest form; you can't just multiply by random numbers and call it simplified.

[Wildt4lon]

14g-(etc.
I'll let you work it out. C'mon this is only lvl 6 maths!

[EkoFox]

I'm going to type out my interpretation and you tell me if I got it wrong:
14 multiplied by variable 'g' minus quantity 5 multiplied by g multiplied by k plus 6 multiplied by x multiplied by y.
You're asking me to evaluate (5gk + 6xy) and subtract the result from 14g.

Right or wrong?

My thought is that you meant 14g(5gk+6xy) (without the subtraction) and wanted me to apply the distributive property.

But you're saying that 14g - (5gk + 6xy) is the same thing as 14g - 5gk - 6xy, right?
