2 hosil qilish uchun -\frac{2}{3} va -3 ni ko'paytirish.

$$2-\left(5\sqrt{4}+4\times 2^{-2}\right)$$

4 ning kvadrat ildizini hisoblab, 2 natijaga ega bo‘ling.

$$2-\left(5\times 2+4\times 2^{-2}\right)$$

10 hosil qilish uchun 5 va 2 ni ko'paytirish.

$$2-\left(10+4\times 2^{-2}\right)$$

-2 daraja ko‘rsatkichini 2 ga hisoblang va \frac{1}{4} ni qiymatni oling.

$$2-\left(10+4\times \frac{1}{4}\right)$$

1 hosil qilish uchun 4 va \frac{1}{4} ni ko'paytirish.

$$2-\left(10+1\right)$$

11 olish uchun 10 va 1'ni qo'shing.
