28 × 12 + 909

1) 28 × 12 = 336

2) 336 + 909 = 1245

320 - 1280 : 8 + 199

1) 1280 : 8 = 160

2) 320 - 160 = 160

160 + 199 = 359

760 : (18 + 20)

1) 18 + 20 = 38

2) 760 : 38 = 20

1008 : 4 + 645

1) 1008 : 4 = 252

2) 252 + 645 = 897

140 × ( 329 - 309)

1)329 - 309 = 20

2) 140 × 20 = 2800

(320 - 64) : 8 + 299

1) 320-64 = 256

2) 256 : 8 = 32

3) 32 + 299 = 331
