Maths in plain C++

Sure - it is. I'm just wondering because I learned that algorithm "officially" the first time at university - not at school. At school we used another technique where you modified the equations to insert them into each other or added / subtracted them to eleminate variables.

Well... gauss does practicaly the same, just with matrices, doesn't it? Sure it is more advanced in details than pen & paper method but the concept is the same. At least that's what it seems to me -- I'm not an expert on this.

Yes, the underlying operations are the same if you don't insert one equation into another. But that's only another way of adding / subtracting with a multiplication.
Maybe I just had the wrong math teachers at school
