# How do they do it? Some companies make awesome software, what is it that gives them results?

Posted on 2002-03-24

Hi

For example, Mathematica is a mathematics program. how does the programmer know how solve his problems with displaying for example a value for n at the top of sigma or summation, then a 2 below summation then a i and a j in smaller print to right of it.

Ive seen the summation symbol in the maths font, and thats all it is, it doesnt contain the other numbers.

How do they do it?

Have they paid Microsoft thousands to help them?

What is it that these programmers know that I dont.

Please help
