Alright, let's solve this math problem step by step. First, we have the number 331. 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 331 and add it to itself 23 times.
Step 1: 0 + 331 = 331
Step 2: 331 + 331 = 662
Step 3: 662 + 331 = 993
Step 4: 993 + 331 = 1324
Step 5: 1324 + 331 = 1655
Step 6: 1655 + 331 = 1986
Step 7: 1986 + 331 = 2317
Step 8: 2317 + 331 = 2648
Step 9: 2648 + 331 = 2979
Step 10: 2979 + 331 = 3310
Step 11: 3310 + 331 = 3641
Step 12: 3641 + 331 = 3972
Step 13: 3972 + 331 = 4303
Step 14: 4303 + 331 = 4634
Step 15: 4634 + 331 = 4965
Step 16: 4965 + 331 = 5296
Step 17: 5296 + 331 = 5627
Step 18: 5627 + 331 = 5958
Step 19: 5958 + 331 = 6289
Step 20: 6289 + 331 = 6620
Step 21: 6620 + 331 = 6951
Step 22: 6951 + 331 = 7282
Step 23: 7282 + 331 = 7613

So, 331*23 = 7613
