Yechim qadamlari

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-1}{-2} kasrini \frac{1}{2} ga soddalashtirish mumkin.

$$\frac{1}{2}-\frac{6}{-2^{2}}$$

2 daraja ko‘rsatkichini 2 ga hisoblang va 4 ni qiymatni oling.

$$\frac{1}{2}-\frac{6}{-4}$$

\frac{6}{-4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{2}-\left(-\frac{3}{2}\right)$$

-\frac{3}{2} ning teskarisi \frac{3}{2} ga teng.

$$\frac{1}{2}+\frac{3}{2}$$

\frac{1}{2} va \frac{3}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1+3}{2}$$

4 olish uchun 1 va 3'ni qo'shing.

$$\frac{4}{2}$$

2 ni olish uchun 4 ni 2 ga bo‘ling.
