$$- 3 [ - 5 + ( 1 - 02 \div 5 ) \div ( - 2 ) ]$$

Baholash

$$\frac{33}{2}=16,5$$

Yechim qadamlari

0 hosil qilish uchun 0 va 2 ni ko'paytirish.

$$-3\left(-5+\frac{1-\frac{0}{5}}{-2}\right)$$

Nol bo‘lmagan har qanday sonni nolga ko‘paytirsangiz, nol bo‘ladi.

$$-3\left(-5+\frac{1}{-2}\right)$$

\frac{1}{-2} kasri manfiy belgini olib tashlash bilan -\frac{1}{2} sifatida qayta yozilishi mumkin.

$$-3\left(-5-\frac{1}{2}\right)$$

-5 ni -\frac{10}{2} kasrga o‘giring.

$$-3\left(-\frac{10}{2}-\frac{1}{2}\right)$$

-\frac{10}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-3\times \frac{-10-1}{2}$$

-11 olish uchun -10 dan 1 ni ayirish.

$$-3\left(-\frac{11}{2}\right)$$

-3\left(-\frac{11}{2}\right) ni yagona kasrga aylantiring.

$$\frac{-3\left(-11\right)}{2}$$

33 hosil qilish uchun -3 va -11 ni ko'paytirish.

$$\frac{33}{2}$$

Omil

$$\frac{3 \cdot 11}{2} = 16\frac{1}{2} = 16,5$$
