Alright, let's solve this math problem step by step. First, we have the number 23. 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 23 and add it to itself 18 times.
Step 1: 0 + 23 = 23
Step 2: 23 + 23 = 46
Step 3: 46 + 23 = 69
Step 4: 69 + 23 = 92
Step 5: 92 + 23 = 115
Step 6: 115 + 23 = 138
Step 7: 138 + 23 = 161
Step 8: 161 + 23 = 184
Step 9: 184 + 23 = 207
Step 10: 207 + 23 = 230
Step 11: 230 + 23 = 253
Step 12: 253 + 23 = 276
Step 13: 276 + 23 = 299
Step 14: 299 + 23 = 322
Step 15: 322 + 23 = 345
Step 16: 345 + 23 = 368
Step 17: 368 + 23 = 391
Step 18: 391 + 23 = 414

So, 23*18 = 414
