Alright, let's solve this math problem step by step. First, we have the number 191. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 18. So, we're going to take the number 191 and add it to itself 18 times.
Step 1: 0 + 191 = 191
Step 2: 191 + 191 = 382
Step 3: 382 + 191 = 573
Step 4: 573 + 191 = 764
Step 5: 764 + 191 = 955
Step 6: 955 + 191 = 1146
Step 7: 1146 + 191 = 1337
Step 8: 1337 + 191 = 1528
Step 9: 1528 + 191 = 1719
Step 10: 1719 + 191 = 1910
Step 11: 1910 + 191 = 2101
Step 12: 2101 + 191 = 2292
Step 13: 2292 + 191 = 2483
Step 14: 2483 + 191 = 2674
Step 15: 2674 + 191 = 2865
Step 16: 2865 + 191 = 3056
Step 17: 3056 + 191 = 3247
Step 18: 3247 + 191 = 3438

So, 191*18 = 3438
