Yechim qadamlari

-2 ni olish uchun 14 ni -7 ga bo‘ling.

$$-3\left(-2-\frac{3\left(47-56\right)}{2}\right)$$

-9 olish uchun 47 dan 56 ni ayirish.

$$-3\left(-2-\frac{3\left(-9\right)}{2}\right)$$

-27 hosil qilish uchun 3 va -9 ni ko'paytirish.

$$-3\left(-2-\frac{-27}{2}\right)$$

\frac{-27}{2} kasri manfiy belgini olib tashlash bilan -\frac{27}{2} sifatida qayta yozilishi mumkin.

$$-3\left(-2-\left(-\frac{27}{2}\right)\right)$$

-\frac{27}{2} ning teskarisi \frac{27}{2} ga teng.

$$-3\left(-2+\frac{27}{2}\right)$$

-2 ni -\frac{4}{2} kasrga o‘giring.

$$-3\left(-\frac{4}{2}+\frac{27}{2}\right)$$

-\frac{4}{2} va \frac{27}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-3\times \frac{-4+27}{2}$$

23 olish uchun -4 va 27'ni qo'shing.

$$-3\times \frac{23}{2}$$

-3\times \frac{23}{2} ni yagona kasrga aylantiring.

$$\frac{-3\times 23}{2}$$

-69 hosil qilish uchun -3 va 23 ni ko'paytirish.

$$\frac{-69}{2}$$

\frac{-69}{2} kasri manfiy belgini olib tashlash bilan -\frac{69}{2} sifatida qayta yozilishi mumkin.

$$-\frac{69}{2}$$

Omil

$$-\frac{69}{2} = -34\frac{1}{2} = -34,5$$
