Alright, let's solve this math problem step by step. First, we have the number 377. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 25. So, we're going to take the number 377 and add it to itself 25 times.
Step 1: 0 + 377 = 377
Step 2: 377 + 377 = 754
Step 3: 754 + 377 = 1131
Step 4: 1131 + 377 = 1508
Step 5: 1508 + 377 = 1885
Step 6: 1885 + 377 = 2262
Step 7: 2262 + 377 = 2639
Step 8: 2639 + 377 = 3016
Step 9: 3016 + 377 = 3393
Step 10: 3393 + 377 = 3770
Step 11: 3770 + 377 = 4147
Step 12: 4147 + 377 = 4524
Step 13: 4524 + 377 = 4901
Step 14: 4901 + 377 = 5278
Step 15: 5278 + 377 = 5655
Step 16: 5655 + 377 = 6032
Step 17: 6032 + 377 = 6409
Step 18: 6409 + 377 = 6786
Step 19: 6786 + 377 = 7163
Step 20: 7163 + 377 = 7540
Step 21: 7540 + 377 = 7917
Step 22: 7917 + 377 = 8294
Step 23: 8294 + 377 = 8671
Step 24: 8671 + 377 = 9048
Step 25: 9048 + 377 = 9425

So, 377*25 = 9425
