Пошаговое объяснение:

1000 - 990 + 500 - 1000 + 20000=19510

1000-990=10

10+500=510

510-1000=-490

-490+20000=19510

Answer 2

To calculate the expression, let's follow the order of operations (PEMDAS/BODMAS):

1000 - 990 + 500 - 1000 + 20000

First, perform the subtraction within the expression:

10 + 500 - 1000 + 20000

Next, perform the addition and subtraction from left to right:

10 + 500 = 510 510 - 1000 = -490 -490 + 20000 = 19510

Therefore, 1000 - 990 + 500 - 1000 + 20000 equals 19510.
