OK, let's crack this. We're given 276 and our task is to multiply it by 34. Essentially, we'll be adding 276 to itself 34 times.
Step 1: 0 + 276 = 276
Step 2: 276 + 276 = 552
Step 3: 552 + 276 = 828
Step 4: 828 + 276 = 1104
Step 5: 1104 + 276 = 1380
Step 6: 1380 + 276 = 1656
Step 7: 1656 + 276 = 1932
Step 8: 1932 + 276 = 2208
Step 9: 2208 + 276 = 2484
Step 10: 2484 + 276 = 2760
Step 11: 2760 + 276 = 3036
Step 12: 3036 + 276 = 3312
Step 13: 3312 + 276 = 3588
Step 14: 3588 + 276 = 3864
Step 15: 3864 + 276 = 4140
Step 16: 4140 + 276 = 4416
Step 17: 4416 + 276 = 4692
Step 18: 4692 + 276 = 4968
Step 19: 4968 + 276 = 5244
Step 20: 5244 + 276 = 5520
Step 21: 5520 + 276 = 5796
Step 22: 5796 + 276 = 6072
Step 23: 6072 + 276 = 6348
Step 24: 6348 + 276 = 6624
Step 25: 6624 + 276 = 6900
Step 26: 6900 + 276 = 7176
Step 27: 7176 + 276 = 7452
Step 28: 7452 + 276 = 7728
Step 29: 7728 + 276 = 8004
Step 30: 8004 + 276 = 8280
Step 31: 8280 + 276 = 8556
Step 32: 8556 + 276 = 8832
Step 33: 8832 + 276 = 9108
Step 34: 9108 + 276 = 9384

So, 276*34 = 9384
