-\frac{1}{2}+7=-12
\frac{1}{-2} kasri manfiy belgini olib tashlash bilan -\frac{1}{2} sifatida qayta yozilishi mumkin.
-\frac{1}{2}+\frac{14}{2}=-12
7 ni \frac{14}{2} kasrga o‘giring.
\frac{-1+14}{2}=-12
-\frac{1}{2} va \frac{14}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.
\frac{13}{2}=-12
13 olish uchun -1 va 14'ni qo'shing.
\frac{13}{2}=-\frac{24}{2}
-12 ni -\frac{24}{2} kasrga o‘giring.
\text{false}
\frac{13}{2} va -\frac{24}{2} ni taqqoslang.
