Yechim qadamlari

4 ni olish uchun 12 ni 3 ga bo‘ling.

$$5+4\left(5-\frac{3}{2}\right)$$

5 ni \frac{10}{2} kasrga o‘giring.

$$5+4\left(\frac{10}{2}-\frac{3}{2}\right)$$

\frac{10}{2} va \frac{3}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$5+4\times \frac{10-3}{2}$$

7 olish uchun 10 dan 3 ni ayirish.

$$5+4\times \frac{7}{2}$$

4\times \frac{7}{2} ni yagona kasrga aylantiring.

$$5+\frac{4\times 7}{2}$$

28 hosil qilish uchun 4 va 7 ni ko'paytirish.

$$5+\frac{28}{2}$$

14 ni olish uchun 28 ni 2 ga bo‘ling.

$$5+14$$

19 olish uchun 5 va 14'ni qo'shing.
