Yechim qadamlari

3 daraja ko‘rsatkichini 7 ga hisoblang va 343 ni qiymatni oling.

$$343+7-\frac{3\left(4-2\times 3\right)}{5}$$

350 olish uchun 343 va 7'ni qo'shing.

$$350-\frac{3\left(4-2\times 3\right)}{5}$$

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$350-\frac{3\left(4-6\right)}{5}$$

-2 olish uchun 4 dan 6 ni ayirish.

$$350-\frac{3\left(-2\right)}{5}$$

-6 hosil qilish uchun 3 va -2 ni ko'paytirish.

$$350-\frac{-6}{5}$$

\frac{-6}{5} kasri manfiy belgini olib tashlash bilan -\frac{6}{5} sifatida qayta yozilishi mumkin.

$$350-\left(-\frac{6}{5}\right)$$

-\frac{6}{5} ning teskarisi \frac{6}{5} ga teng.

$$350+\frac{6}{5}$$

350 ni \frac{1750}{5} kasrga o‘giring.

$$\frac{1750}{5}+\frac{6}{5}$$

\frac{1750}{5} va \frac{6}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1750+6}{5}$$

1756 olish uchun 1750 va 6'ni qo'shing.

$$\frac{1756}{5}$$

Omil

$$\frac{2 ^ {2} \cdot 439}{5} = 351\frac{1}{5} = 351,2$$
