(25.200:7+802370):4-32.0489:(48+24)= 60.90090-648408+383.384-8423=

Первый пример.

(25 200 : 7 + 802 * 370) : 4 - 32 048 * 9 : (48 + 24) = 71 079;

25 200 / 7 = 3600;

802 * 370 = 296 740;

3600 + 296 740 = 300 340;

300 340 / 4 = 75 085;

32 048 * 9 = 288 432;

48 + 24 = 72;

288 432 / 72 = 4006;

75 085 - 4006 = 71 079.

2-ой пример.

60 900 * 90 - 648 * 408 + 383 384 - 84 * 23 = 5 598 068;

60 900 * 90 = 5 481 000;

648 * 408 = 264 384;

5 481 000 - 264 384 = 5 216 616;

5 216 616 + 383 384 = 5 600 000;

4 * 23 = 1932;

5 600 000 - 1932 = 5 598 068.
