Alright, let's solve this math problem step by step. First, we have the number 187. 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 187 and add it to itself 25 times.
Step 1: 0 + 187 = 187
Step 2: 187 + 187 = 374
Step 3: 374 + 187 = 561
Step 4: 561 + 187 = 748
Step 5: 748 + 187 = 935
Step 6: 935 + 187 = 1122
Step 7: 1122 + 187 = 1309
Step 8: 1309 + 187 = 1496
Step 9: 1496 + 187 = 1683
Step 10: 1683 + 187 = 1870
Step 11: 1870 + 187 = 2057
Step 12: 2057 + 187 = 2244
Step 13: 2244 + 187 = 2431
Step 14: 2431 + 187 = 2618
Step 15: 2618 + 187 = 2805
Step 16: 2805 + 187 = 2992
Step 17: 2992 + 187 = 3179
Step 18: 3179 + 187 = 3366
Step 19: 3366 + 187 = 3553
Step 20: 3553 + 187 = 3740
Step 21: 3740 + 187 = 3927
Step 22: 3927 + 187 = 4114
Step 23: 4114 + 187 = 4301
Step 24: 4301 + 187 = 4488
Step 25: 4488 + 187 = 4675

So, 187*25 = 4675
