Alright, let's solve this math problem step by step. First, we have the number 61. 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 61 and add it to itself 25 times.
Step 1: 0 + 61 = 61
Step 2: 61 + 61 = 122
Step 3: 122 + 61 = 183
Step 4: 183 + 61 = 244
Step 5: 244 + 61 = 305
Step 6: 305 + 61 = 366
Step 7: 366 + 61 = 427
Step 8: 427 + 61 = 488
Step 9: 488 + 61 = 549
Step 10: 549 + 61 = 610
Step 11: 610 + 61 = 671
Step 12: 671 + 61 = 732
Step 13: 732 + 61 = 793
Step 14: 793 + 61 = 854
Step 15: 854 + 61 = 915
Step 16: 915 + 61 = 976
Step 17: 976 + 61 = 1037
Step 18: 1037 + 61 = 1098
Step 19: 1098 + 61 = 1159
Step 20: 1159 + 61 = 1220
Step 21: 1220 + 61 = 1281
Step 22: 1281 + 61 = 1342
Step 23: 1342 + 61 = 1403
Step 24: 1403 + 61 = 1464
Step 25: 1464 + 61 = 1525

So, 61*25 = 1525
