Yechim qadamlari

14 hosil qilish uchun 7 va 2 ni ko'paytirish.

$$6-\frac{14+1}{2}\left(2-\frac{1\times 3+1}{3}\right)$$

15 olish uchun 14 va 1'ni qo'shing.

$$6-\frac{15}{2}\left(2-\frac{1\times 3+1}{3}\right)$$

3 hosil qilish uchun 1 va 3 ni ko'paytirish.

$$6-\frac{15}{2}\left(2-\frac{3+1}{3}\right)$$

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

$$6-\frac{15}{2}\left(2-\frac{4}{3}\right)$$

2 ni \frac{6}{3} kasrga o‘giring.

$$6-\frac{15}{2}\left(\frac{6}{3}-\frac{4}{3}\right)$$

\frac{6}{3} va \frac{4}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$6-\frac{15}{2}\times \frac{6-4}{3}$$

2 olish uchun 6 dan 4 ni ayirish.

$$6-\frac{15}{2}\times \frac{2}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{15}{2} ni \frac{2}{3} ga ko‘paytiring.

$$6-\frac{15\times 2}{2\times 3}$$

Surat va maxrajdagi ikkala 2 ni qisqartiring.

$$6-\frac{15}{3}$$

5 ni olish uchun 15 ni 3 ga bo‘ling.
