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 23. So, we're going to take the number 161 and add it to itself 23 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
Step 14: 2093 + 161 = 2254
Step 15: 2254 + 161 = 2415
Step 16: 2415 + 161 = 2576
Step 17: 2576 + 161 = 2737
Step 18: 2737 + 161 = 2898
Step 19: 2898 + 161 = 3059
Step 20: 3059 + 161 = 3220
Step 21: 3220 + 161 = 3381
Step 22: 3381 + 161 = 3542
Step 23: 3542 + 161 = 3703

So, 161*23 = 3703
