Elementär algebra

Elementär algebra är algebra som beskriver hur man omvandlar matematiska uttryck, framför allt polynom, för att lösa ekvationer. Till skillnad från aritmetiken, som arbetar med tal bestående av siffror, använder sig algebran av bokstäver som betecknar variabler. Då kan man skriva allmängiltiga formler. Denna utveckling kallas den symboliska abstraktionen och skedde på 1600-talet.

How to factor the trinomial :

x y - x + y - 1

https://math.stackexchange.com/questions/1811972/how-to-factor-the-trinomial-xy-xy-1

x y - x + y - 1 = x \cdot (y - 1) + 1 \cdot (y - 1) = (x + 1) (y - 1)

x y - x + y - 1 = x y + y - x - 1 = (x + 1) \cdot y + (x + 1) \cdot - 1 = (x + 1) (y - 1)

Three Diophantine equations in three variables, finding

x + y + z

https://math.stackexchange.com/q/1932703

Add the first and second equations together:

13 x - 7 y - z = 0

z = 13 x - 7 y

Now substitute back into the first equation to eliminate

z

9 x + y - 8 (13 x - 7 y) = 0

- 95 x + 57 y = 0

3 y = 5 x

Since all variables ...
