Re: Definition question

Hi;

When you factor an integer n it will always have 4 trivial factors (-1,1,-n,n) all the other factors are non trivial.


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Definition question

Hi;

For one thing factoring helps reduce fractions. It is a basic skill that comes up in simplification of complicated expressions. Since math began thousands of years ago people have been fascinated by prime numbers. Since composites are not prime and are made up of prime factors the natural question is what are those factors. You find them by factoring.
