Answer 1

Ответ:

1)60: 2+250:5+70x7+90=660

2)9 80x8+20x4+3x 80-60=8100

3)7 280:70+9x90+4x40=1074

4)незнаю там получается -54

5)20x9+240: 80 - 160:40 =179

6)4x90-2x 20+80x6+70=870

7)720: 8+80x5-560: 80 =483

8)40x7+450:90-240:30=277

9)20 x 6+30x9+2x30-40=410

10)360:90+3x70-140:2=144

11)9x20-(7x20-240:8)=70

12)4x90-40:20-450:90=353

Answer 2

To solve these expressions, let's break them down step by step:

1. 60:2 + 250:5 + 70*7 + 90 = 30 + 50 + 490 + 90 = 660

2. 9808 + 204 + 3*80 - 60 = 7840 + 80 + 240 - 60 = 8140

3. 280:70 + 990 + 440 = 4 + 810 + 160 = 974

4. 660 - (690 - 270:3):5 = 360 - (540 - 90):5 = 360 - 90:5 = 360 - 18 = 342

5. 20*9 + 240:80 - 160:40 = 180 + 3 - 4 = 179

6. 490 - 220 + 80*6 + 70 = 360 - 40 + 480 + 70 = 870

7. 720:8 + 80*5 - 560:80 = 90 + 400 - 7 = 483

8. 40*7 + 450:90 - 240:30 = 280 + 5 - 8 = 277

9. 206 + 309 + 2*30 - 40 = 120 + 270 + 60 - 40 = 410

10. 360:90 + 3*70 - 140:2 = 4 + 210 - 70 = 144

11. 920 - (720 - 240:8) = 180 - (140 - 30) = 180 - 110 = 70

12. 4*90 - 40:20 - 450:90 = 360 - 2 - 5 = 353

So, the results of the expressions are as follows:

1. 660
2. 8140
3. 974
4. 342
5. 179
6. 870
7. 483
8. 277
9. 410
10. 144
11. 70
12. 353
