Without delay, let's solve this. We've got 14 and we will be multiplying it by 25, that is, adding 14 to itself 25 times.
Step 1: 0 + 14 = 14
Step 2: 14 + 14 = 28
Step 3: 28 + 14 = 42
Step 4: 42 + 14 = 56
Step 5: 56 + 14 = 70
Step 6: 70 + 14 = 84
Step 7: 84 + 14 = 98
Step 8: 98 + 14 = 112
Step 9: 112 + 14 = 126
Step 10: 126 + 14 = 140
Step 11: 140 + 14 = 154
Step 12: 154 + 14 = 168
Step 13: 168 + 14 = 182
Step 14: 182 + 14 = 196
Step 15: 196 + 14 = 210
Step 16: 210 + 14 = 224
Step 17: 224 + 14 = 238
Step 18: 238 + 14 = 252
Step 19: 252 + 14 = 266
Step 20: 266 + 14 = 280
Step 21: 280 + 14 = 294
Step 22: 294 + 14 = 308
Step 23: 308 + 14 = 322
Step 24: 322 + 14 = 336
Step 25: 336 + 14 = 350

So, 14*25 = 350
