how can i prove math problems?

Answer 1

There's proof by deduction, proof by process of elimination, proof by contradiction and proof by induction.

Answer 2

There is no easy answer to this question, because it depends on the nature of what one is trying to prove. Some proofs are quite simple, like the ones usually done in algebra or geometry class. Others are very complex and defy even the most gifted mathematical minds. Fermat's Last Theorem is a famous example of this. Here's a link in case you're interested in pursuing this further.

It took more than three centuries to finally pin down the proof of Fermat's conjecture. And much of the mathematics used to prove it didn't even exist during Fermat's day. Which begs the question: How does one know that Fermat's proof was correct? We don't, because it was never found among his papers after his death.

Answer 3

Have a understanding of math concerning

P = Parenthesis

E = Exponents

D = division

M = Multiplication

A = Addition

S = Subtraction

Negative Numbers

Inequalities: Multiplication and division all inequalities signs changes.

Parenthesis: if a negative number preceeds a parenthesis all + change to - and all - change to +

The expression - (x -3) It is understood that - sign means - 1. the expression becomes - 1(x - 3) and simplify.

Answer 4

something divided through 0 is undefined in mathematics. Your first 2 statements are not actual... and hence your very last actuality isn't actual both. If 2/0 = 0 were actual, then I should be able to multiply through 0 on each area and get a real actuality 2 = 0*0 2 = 0 yet all of us comprehend that's no longer properly, is it? in case you want some extra examples of invalid proofs, examine out Wikipedia less than. Your invalid info has similarities to the single given interior the area entitled "info that each one numbers are equivalent"

Answer 5

It usually goes like this:

You have an equation, like:

(2c+b*b)/c=2+b*h

And, using known facts (let's say, that we know that it is a rule that b/c=h) you have to show that the right side of the equation equals the left side.

like:

L=(2c+b*b)/c=2c/c + b*b/c= 2+b*b/c=2+b*h=R

(L means left side of the equation, r means right side)

which ends the proof (or wetp)

(In the example we started from the left and changed it until we got right side, but you can go starting from the right side, it doesn't matter really)

At least that is what we do it like on our maths. Obviously, there are certain methods for different branches and subjects of maths, so to give you closer information I would have to know what do you have to proof, and what section of math is it.
