Alright, let's solve this math problem step by step. First, we have the number 161. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 13. So, we're going to take the number 161 and add it to itself 13 times.
Step 1: 0 + 161 = 161
Step 2: 161 + 161 = 322
Step 3: 322 + 161 = 483
Step 4: 483 + 161 = 644
Step 5: 644 + 161 = 805
Step 6: 805 + 161 = 966
Step 7: 966 + 161 = 1127
Step 8: 1127 + 161 = 1288
Step 9: 1288 + 161 = 1449
Step 10: 1449 + 161 = 1610
Step 11: 1610 + 161 = 1771
Step 12: 1771 + 161 = 1932
Step 13: 1932 + 161 = 2093

So, 161*13 = 2093
