2-6\left(\frac{3}{6}-\frac{4}{6}+\frac{5}{6}\right)
2 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{1}{2} va \frac{2}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.
2-6\left(\frac{3-4}{6}+\frac{5}{6}\right)
\frac{3}{6} va \frac{4}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.
2-6\left(-\frac{1}{6}+\frac{5}{6}\right)
-1 olish uchun 3 dan 4 ni ayirish.
2-6\times \frac{-1+5}{6}
-\frac{1}{6} va \frac{5}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.
2-6\times \frac{4}{6}
4 olish uchun -1 va 5'ni qo'shing.
2-6\times \frac{2}{3}
\frac{4}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
2-\frac{6\times 2}{3}
6\times \frac{2}{3} ni yagona kasrga aylantiring.
