Sure thing, let's get straight to it. We start with 117 and we're going to multiply it by 11, which means adding 117 to itself 11 times.
Step 1: 0 + 117 = 117
Step 2: 117 + 117 = 234
Step 3: 234 + 117 = 351
Step 4: 351 + 117 = 468
Step 5: 468 + 117 = 585
Step 6: 585 + 117 = 702
Step 7: 702 + 117 = 819
Step 8: 819 + 117 = 936
Step 9: 936 + 117 = 1053
Step 10: 1053 + 117 = 1170
Step 11: 1170 + 117 = 1287

So, 117*11 = 1287
