Решим каждый пример по действиям:

1. 648 720 : 68 + 506 * 108 - 63 295

1. $$648720 : 68 = 9540$$


2. $$506 \cdot 108 = 54648$$


3. $$9540 + 54648 = 64188$$


4. $$64188 - 63295 = 893$$

2. 608 * 506 - 236 * 400 + 8716

1. $$608 \cdot 506 = 307648$$


2. $$236 \cdot 400 = 94400$$


3. $$307648 - 94400 = 213248$$


4. $$213248 + 8716 = 221964$$

3. 286 996 : (1 010 - 553) + 164 268 : 324

1. $$1010 - 553 = 457$$


2. $$286996 : 457 = 628$$


3. $$164268 : 324 = 507$$


4. $$628 + 507 = 1135$$

4. 1 000 000 - (700 800 + 425 * 704) + 25

1. $$425 \cdot 704 = 299600$$


2. $$700800 + 299600 = 1000400$$


3. $$1000000 - 1000400 = -400$$


4. $$-400 + 25 = -375$$
