Alright, let's solve this math problem step by step. First, we have the number 65. 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 65 and add it to itself 25 times.
Step 1: 0 + 65 = 65
Step 2: 65 + 65 = 130
Step 3: 130 + 65 = 195
Step 4: 195 + 65 = 260
Step 5: 260 + 65 = 325
Step 6: 325 + 65 = 390
Step 7: 390 + 65 = 455
Step 8: 455 + 65 = 520
Step 9: 520 + 65 = 585
Step 10: 585 + 65 = 650
Step 11: 650 + 65 = 715
Step 12: 715 + 65 = 780
Step 13: 780 + 65 = 845
Step 14: 845 + 65 = 910
Step 15: 910 + 65 = 975
Step 16: 975 + 65 = 1040
Step 17: 1040 + 65 = 1105
Step 18: 1105 + 65 = 1170
Step 19: 1170 + 65 = 1235
Step 20: 1235 + 65 = 1300
Step 21: 1300 + 65 = 1365
Step 22: 1365 + 65 = 1430
Step 23: 1430 + 65 = 1495
Step 24: 1495 + 65 = 1560
Step 25: 1560 + 65 = 1625

So, 65*25 = 1625
