Alright, let's solve this math problem step by step. First, we have the number 602. 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 602 and add it to itself 25 times.
Step 1: 0 + 602 = 602
Step 2: 602 + 602 = 1204
Step 3: 1204 + 602 = 1806
Step 4: 1806 + 602 = 2408
Step 5: 2408 + 602 = 3010
Step 6: 3010 + 602 = 3612
Step 7: 3612 + 602 = 4214
Step 8: 4214 + 602 = 4816
Step 9: 4816 + 602 = 5418
Step 10: 5418 + 602 = 6020
Step 11: 6020 + 602 = 6622
Step 12: 6622 + 602 = 7224
Step 13: 7224 + 602 = 7826
Step 14: 7826 + 602 = 8428
Step 15: 8428 + 602 = 9030
Step 16: 9030 + 602 = 9632
Step 17: 9632 + 602 = 10234
Step 18: 10234 + 602 = 10836
Step 19: 10836 + 602 = 11438
Step 20: 11438 + 602 = 12040
Step 21: 12040 + 602 = 12642
Step 22: 12642 + 602 = 13244
Step 23: 13244 + 602 = 13846
Step 24: 13846 + 602 = 14448
Step 25: 14448 + 602 = 15050

So, 602*25 = 15050
