Yechim qadamlari

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

$$\frac{100}{4}-\frac{-2}{-\frac{2}{3}}-2$$

25 ni olish uchun 100 ni 4 ga bo‘ling.

$$25-\frac{-2}{-\frac{2}{3}}-2$$

-2 ni -\frac{2}{3} ga bo'lish -2 ga k'paytirish -\frac{2}{3} ga qaytarish.

$$25-\left(-2\left(-\frac{3}{2}\right)\right)-2$$

-2 ni -\frac{3}{2} marotabaga ko'paytirish.

$$25-3-2$$

22 olish uchun 25 dan 3 ni ayirish.

$$22-2$$

20 olish uchun 22 dan 2 ni ayirish.

$$20$$
