Sure thing! We've got 113 and we're gonna multiply it by 25. That's the same as adding 113 to itself 25 times.
Step 1: 0 + 113 = 113
Step 2: 113 + 113 = 226
Step 3: 226 + 113 = 339
Step 4: 339 + 113 = 452
Step 5: 452 + 113 = 565
Step 6: 565 + 113 = 678
Step 7: 678 + 113 = 791
Step 8: 791 + 113 = 904
Step 9: 904 + 113 = 1017
Step 10: 1017 + 113 = 1130
Step 11: 1130 + 113 = 1243
Step 12: 1243 + 113 = 1356
Step 13: 1356 + 113 = 1469
Step 14: 1469 + 113 = 1582
Step 15: 1582 + 113 = 1695
Step 16: 1695 + 113 = 1808
Step 17: 1808 + 113 = 1921
Step 18: 1921 + 113 = 2034
Step 19: 2034 + 113 = 2147
Step 20: 2147 + 113 = 2260
Step 21: 2260 + 113 = 2373
Step 22: 2373 + 113 = 2486
Step 23: 2486 + 113 = 2599
Step 24: 2599 + 113 = 2712
Step 25: 2712 + 113 = 2825

So, 113*25 = 2825
