Let's get this math done. We have 127 and we're going to multiply it by 10. This is the same as taking 127 and adding it to itself 10 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
Step 10: 1143 + 127 = 1270

So, 127*10 = 1270
