Alright, let's solve this math problem step by step. First, we have the number 25. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 41. So, we're going to take the number 25 and add it to itself 41 times.
Step 1: 0 + 25 = 25
Step 2: 25 + 25 = 50
Step 3: 50 + 25 = 75
Step 4: 75 + 25 = 100
Step 5: 100 + 25 = 125
Step 6: 125 + 25 = 150
Step 7: 150 + 25 = 175
Step 8: 175 + 25 = 200
Step 9: 200 + 25 = 225
Step 10: 225 + 25 = 250
Step 11: 250 + 25 = 275
Step 12: 275 + 25 = 300
Step 13: 300 + 25 = 325
Step 14: 325 + 25 = 350
Step 15: 350 + 25 = 375
Step 16: 375 + 25 = 400
Step 17: 400 + 25 = 425
Step 18: 425 + 25 = 450
Step 19: 450 + 25 = 475
Step 20: 475 + 25 = 500
Step 21: 500 + 25 = 525
Step 22: 525 + 25 = 550
Step 23: 550 + 25 = 575
Step 24: 575 + 25 = 600
Step 25: 600 + 25 = 625
Step 26: 625 + 25 = 650
Step 27: 650 + 25 = 675
Step 28: 675 + 25 = 700
Step 29: 700 + 25 = 725
Step 30: 725 + 25 = 750
Step 31: 750 + 25 = 775
Step 32: 775 + 25 = 800
Step 33: 800 + 25 = 825
Step 34: 825 + 25 = 850
Step 35: 850 + 25 = 875
Step 36: 875 + 25 = 900
Step 37: 900 + 25 = 925
Step 38: 925 + 25 = 950
Step 39: 950 + 25 = 975
Step 40: 975 + 25 = 1000
Step 41: 1000 + 25 = 1025

So, 25*41 = 1025
