Who understands Maths (serious question) HELP TREV!

[TREVCOS]

That does make more sense. As said, the answers are in the back, but not the workings and i need to see workings to understand where i'm going wrong. The examples were pretty basic as well. Thanks very much. I'm sure there will be worse to come but i'll know where to come when i get stuck.

No problem mate. I'll try.....I might have to ask the audience if they get too complex.

My maths teacher would be proud, actually he wouldn't because he hated me and I hated him.

Hello, it's me again lol. A question....again lol.

In the example we had that ended 16t - v. Why did it end that way? Why did it not end 16t - -v? After all, 16t -v seems to show that it's 16t - +v. If you know what i mean? That's why I asked if it was just showing the 2 different values, instead of the bottom line being looking like a sum. I hope you know what i mean (because i don't lol)

When you say it's 16t - +v you're right, that exactly what it is, but because it is a minus and you're subtracting a positive value you don't need to show the + sign. Does that make sense?

its because a minus, minus becomes a plus fella iirc.

Yeah that's where im getting confused. The second line of the equation reads:

7t + 9t - -3v - 4v

So to me that reads: negative negative 3v minus 4v, which changes to +3v - 4v, which is -v. Therefor the end line should read 16t - -v, but if the 2 -- in the final line turn to a +, why is it not 16t + v?

Oh my god, i'm even confusing myself. Think i'll just get drunk.

A little late but for my 2-penneth:

Once you have use the signs (+ - ) you forget them and just stick with what is left.

" - - 3V -4V = -1V " (the result of the equation)

The equations never really have an answer, you have to simplify them as far as possible

In maths
A minus and a mines make a plus
A plus and a plus make a plus
A plus and a minus make a minus

I think that's my problem, i'm looking for a final answer, like 10 - 6 = 4. I also think i'm analysing it to much and just confusing myself. More practice required.

Yes, that makes perfect sense to me. Thanks again for all the help.

i,ll second that is any of that in english cos that means nowt to me probably why am a plasterer

5x^-2y^10 over 2x^-1(-3x^-3y^-1)^-2

Try this?

That's exactly it Gaz.

What I was going to say as well is you're not looking for a numeric answer here, so you won't get 5 for example because you don't have any specific values for t and v. If there was a key that said, for example t = 10 and v = 5 then you could actually work out a numeric answer.

So using that key your simplified 16t - v would equal (16 x 10 = 160) - 5 so simplified down again that's 160 - 5 = 155.
