решите два выражения
64/4+39/(60-47)+24*7=

28*7-(32-16)/4+51/17-14=

64/4+39/(60-47)+24х7=187

28х7-(32-16)/4+51/17-14=181

вроде так

64/4 + 39/(60 - 47) + 24 * 7 = 187

1) 60 - 47 = 13

2) 39/13 = 39 : 13 = 3

3) 64/4 = 64 : 4 = 16

4) 24 * 7 = 168

5) 16 + 3 = 19

6) 19 + 168 = 187

28 * 7 - (32 - 16)/4 + 51/17 - 14 = 181

1) 32 - 16 = 16

2) 16/4 = 16 : 4 = 4

3) 28 * 7 = 196

4) 51/17 = 51 : 17 = 3

5) 196 - 4 = 192

6) 192 + 3 = 195

7) 195 - 14 = 181
