$$\frac{18}{16}+\frac{5}{16}+\frac{-7}{16}$$

\frac{18}{16} va \frac{5}{16} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{18+5}{16}+\frac{-7}{16}$$

23 olish uchun 18 va 5'ni qo'shing.

$$\frac{23}{16}+\frac{-7}{16}$$

\frac{-7}{16} kasri manfiy belgini olib tashlash bilan -\frac{7}{16} sifatida qayta yozilishi mumkin.

$$\frac{23}{16}-\frac{7}{16}$$

\frac{23}{16} va \frac{7}{16} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{23-7}{16}$$
