Let's get this math done. We have 57 and we're going to multiply it by 25. This is the same as taking 57 and adding it to itself 25 times.
Step 1: 0 + 57 = 57
Step 2: 57 + 57 = 114
Step 3: 114 + 57 = 171
Step 4: 171 + 57 = 228
Step 5: 228 + 57 = 285
Step 6: 285 + 57 = 342
Step 7: 342 + 57 = 399
Step 8: 399 + 57 = 456
Step 9: 456 + 57 = 513
Step 10: 513 + 57 = 570
Step 11: 570 + 57 = 627
Step 12: 627 + 57 = 684
Step 13: 684 + 57 = 741
Step 14: 741 + 57 = 798
Step 15: 798 + 57 = 855
Step 16: 855 + 57 = 912
Step 17: 912 + 57 = 969
Step 18: 969 + 57 = 1026
Step 19: 1026 + 57 = 1083
Step 20: 1083 + 57 = 1140
Step 21: 1140 + 57 = 1197
Step 22: 1197 + 57 = 1254
Step 23: 1254 + 57 = 1311
Step 24: 1311 + 57 = 1368
Step 25: 1368 + 57 = 1425

So, 57*25 = 1425
