Yechim qadamlari

180 hosil qilish uchun 2 va 90 ni ko'paytirish.

$$180+\left(11-2\right)\times 120=\left(277-4\right)\times 90$$

9 olish uchun 11 dan 2 ni ayirish.

$$180+9\times 120=\left(277-4\right)\times 90$$

1080 hosil qilish uchun 9 va 120 ni ko'paytirish.

$$180+1080=\left(277-4\right)\times 90$$

1260 olish uchun 180 va 1080'ni qo'shing.

$$1260=\left(277-4\right)\times 90$$

273 olish uchun 277 dan 4 ni ayirish.

$$1260=273\times 90$$

24570 hosil qilish uchun 273 va 90 ni ko'paytirish.

$$1260=24570$$

1260 va 24570 ni taqqoslang.
