Yechim qadamlari

3 daraja ko‘rsatkichini 2 ga hisoblang va 8 ni qiymatni oling.

$$8\left(9-2\right)+\frac{12}{4}-|-5|$$

7 olish uchun 9 dan 2 ni ayirish.

$$8\times 7+\frac{12}{4}-|-5|$$

56 hosil qilish uchun 8 va 7 ni ko'paytirish.

$$56+\frac{12}{4}-|-5|$$

3 ni olish uchun 12 ni 4 ga bo‘ling.

$$56+3-|-5|$$

59 olish uchun 56 va 3'ni qo'shing.

$$59-|-5|$$

a haqiqiy sonining mutloq qiymati qachon a\geq 0 bo‘lganda, a yoki qachon a<0 bo‘lganda -a. -5 ning mutloq qiymati 5 ga teng.

$$59-5$$

54 olish uchun 59 dan 5 ni ayirish.
