[2430-6*(723-319)]*2+488= 1428:[(1500-1496)*5+2*11]-34= [7*216-(512+548)+2*324]:11=

Первый пример.

[2430 - 6 * (723 - 319)] * 2 + 488 = 500;

723 - 319 = 404;

6 * 404 = 2424;

2430 - 2424 = 6;

6 * 2 = 12;

12 + 488 = 500.

Второй пример.

1428 : [(1500 - 1496) * 5 + 2 * 11] - 34 = 0;

1500 - 1496 = 4;

4 * 5 = 20;

2 * 11 = 22;

20 + 22 = 42;

1428 / 42 = 34;

34 - 34 = 0.

Третий пример.

[7 * 216 - (512 + 548) + 2 * 324] : 11 = 100;

7 * 216 = 1512;

512 + 548 = 1060;

1512 - 1060 = 452;

2 * 324 = 648;

452 + 648 = 1100;

1100 / 11 = 100.
