Let's get this math done. We have 181 and we're going to multiply it by 18. This is the same as taking 181 and adding it to itself 18 times.
Step 1: 0 + 181 = 181
Step 2: 181 + 181 = 362
Step 3: 362 + 181 = 543
Step 4: 543 + 181 = 724
Step 5: 724 + 181 = 905
Step 6: 905 + 181 = 1086
Step 7: 1086 + 181 = 1267
Step 8: 1267 + 181 = 1448
Step 9: 1448 + 181 = 1629
Step 10: 1629 + 181 = 1810
Step 11: 1810 + 181 = 1991
Step 12: 1991 + 181 = 2172
Step 13: 2172 + 181 = 2353
Step 14: 2353 + 181 = 2534
Step 15: 2534 + 181 = 2715
Step 16: 2715 + 181 = 2896
Step 17: 2896 + 181 = 3077
Step 18: 3077 + 181 = 3258

So, 181*18 = 3258
