Alright, let's solve this math problem step by step. First, we have the number 887. 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 887 and add it to itself 25 times.
Step 1: 0 + 887 = 887
Step 2: 887 + 887 = 1774
Step 3: 1774 + 887 = 2661
Step 4: 2661 + 887 = 3548
Step 5: 3548 + 887 = 4435
Step 6: 4435 + 887 = 5322
Step 7: 5322 + 887 = 6209
Step 8: 6209 + 887 = 7096
Step 9: 7096 + 887 = 7983
Step 10: 7983 + 887 = 8870
Step 11: 8870 + 887 = 9757
Step 12: 9757 + 887 = 10644
Step 13: 10644 + 887 = 11531
Step 14: 11531 + 887 = 12418
Step 15: 12418 + 887 = 13305
Step 16: 13305 + 887 = 14192
Step 17: 14192 + 887 = 15079
Step 18: 15079 + 887 = 15966
Step 19: 15966 + 887 = 16853
Step 20: 16853 + 887 = 17740
Step 21: 17740 + 887 = 18627
Step 22: 18627 + 887 = 19514
Step 23: 19514 + 887 = 20401
Step 24: 20401 + 887 = 21288
Step 25: 21288 + 887 = 22175

So, 887*25 = 22175
