OK, let's work through this together. We're starting with 127 and we're going to multiply it by 9, which means we add 127 to itself 9 times.
Step 1: 0 + 127 = 127
Step 2: 127 + 127 = 254
Step 3: 254 + 127 = 381
Step 4: 381 + 127 = 508
Step 5: 508 + 127 = 635
Step 6: 635 + 127 = 762
Step 7: 762 + 127 = 889
Step 8: 889 + 127 = 1016
Step 9: 1016 + 127 = 1143

So, 127*9 = 1143
