Alright, let's solve this math problem step by step. First, we have the number 913. 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 913 and add it to itself 25 times.
Step 1: 0 + 913 = 913
Step 2: 913 + 913 = 1826
Step 3: 1826 + 913 = 2739
Step 4: 2739 + 913 = 3652
Step 5: 3652 + 913 = 4565
Step 6: 4565 + 913 = 5478
Step 7: 5478 + 913 = 6391
Step 8: 6391 + 913 = 7304
Step 9: 7304 + 913 = 8217
Step 10: 8217 + 913 = 9130
Step 11: 9130 + 913 = 10043
Step 12: 10043 + 913 = 10956
Step 13: 10956 + 913 = 11869
Step 14: 11869 + 913 = 12782
Step 15: 12782 + 913 = 13695
Step 16: 13695 + 913 = 14608
Step 17: 14608 + 913 = 15521
Step 18: 15521 + 913 = 16434
Step 19: 16434 + 913 = 17347
Step 20: 17347 + 913 = 18260
Step 21: 18260 + 913 = 19173
Step 22: 19173 + 913 = 20086
Step 23: 20086 + 913 = 20999
Step 24: 20999 + 913 = 21912
Step 25: 21912 + 913 = 22825

So, 913*25 = 22825
