Alright, let's solve this math problem step by step. First, we have the number 411. 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 411 and add it to itself 25 times.
Step 1: 0 + 411 = 411
Step 2: 411 + 411 = 822
Step 3: 822 + 411 = 1233
Step 4: 1233 + 411 = 1644
Step 5: 1644 + 411 = 2055
Step 6: 2055 + 411 = 2466
Step 7: 2466 + 411 = 2877
Step 8: 2877 + 411 = 3288
Step 9: 3288 + 411 = 3699
Step 10: 3699 + 411 = 4110
Step 11: 4110 + 411 = 4521
Step 12: 4521 + 411 = 4932
Step 13: 4932 + 411 = 5343
Step 14: 5343 + 411 = 5754
Step 15: 5754 + 411 = 6165
Step 16: 6165 + 411 = 6576
Step 17: 6576 + 411 = 6987
Step 18: 6987 + 411 = 7398
Step 19: 7398 + 411 = 7809
Step 20: 7809 + 411 = 8220
Step 21: 8220 + 411 = 8631
Step 22: 8631 + 411 = 9042
Step 23: 9042 + 411 = 9453
Step 24: 9453 + 411 = 9864
Step 25: 9864 + 411 = 10275

So, 411*25 = 10275
