Yechim qadamlari

-58 olish uchun -37 dan 21 ni ayirish.

$$|-58+54-\frac{1}{2}|$$

-4 olish uchun -58 va 54'ni qo'shing.

$$|-4-\frac{1}{2}|$$

-4 ni -\frac{8}{2} kasrga o‘giring.

$$|-\frac{8}{2}-\frac{1}{2}|$$

-\frac{8}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$|\frac{-8-1}{2}|$$

-9 olish uchun -8 dan 1 ni ayirish.

$$|-\frac{9}{2}|$$

a haqiqiy sonining mutloq qiymati qachon a\geq 0 bo‘lganda, a yoki qachon a<0 bo‘lganda -a. -\frac{9}{2} ning mutloq qiymati \frac{9}{2} ga teng.

$$\frac{9}{2}$$

Omil

$$\frac{3 ^ {2}}{2} = 4\frac{1}{2} = 4,5$$
