OK, let's work through this together. We're starting with 276 and we're going to multiply it by 8, which means we add 276 to itself 8 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

So, 276*8 = 2208
