Tara kasta oo idil waxaa lagu muujin karaa dhibco. Tilmaan ahaan 6 waxaa lagu muujin karaa siyaabahaa  

...... ama ::::  Tirooyinka u dhigmi kara laydi ahaan ayaa ah tirooyin leh isirro maratal tirada 12 = 6 X 2 = 3 X 4 

Raadinta isirka ax + by + ay + bx

Furfuris: ax + by + ay + bx = ax + bx + ay + by
                             Xeerka kala hormarinta isugaynta
                            = ( ax + bx) + ( ay + by)
                            Xeerka hormagalinta isugaynta
                           = x(a + b)  + y (a + b)
                           Xeerka kala dhigga iskudhufashada ee isugaynta
                          = (a + b) (x + y)
                          Xeerka kala dhigga iskudhufashada ee isugeynta
 Markaa ax + by + ay + bx = (a + b) (x + y)
