Yechim qadamlari

2 daraja ko‘rsatkichini 2 ga hisoblang va 4 ni qiymatni oling.

$$4+\frac{-7}{-\frac{1\times 4+3}{4}}$$

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

$$4+\frac{-7}{-\frac{4+3}{4}}$$

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

$$4+\frac{-7}{-\frac{7}{4}}$$

-7 ni -\frac{7}{4} ga bo'lish -7 ga k'paytirish -\frac{7}{4} ga qaytarish.

$$4-7\left(-\frac{4}{7}\right)$$

-7 ni -\frac{4}{7} marotabaga ko'paytirish.

$$4+4$$

8 olish uchun 4 va 4'ni qo'shing.

$$8$$
