OK, let's crack this. We're given 276 and our task is to multiply it by 10. Essentially, we'll be adding 276 to itself 10 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

So, 276*10 = 2760
