Let's roll up our sleeves and solve this. We have 194 and we're going to multiply it by 25, essentially adding 194 to itself 25 times.
Step 1: 0 + 194 = 194
Step 2: 194 + 194 = 388
Step 3: 388 + 194 = 582
Step 4: 582 + 194 = 776
Step 5: 776 + 194 = 970
Step 6: 970 + 194 = 1164
Step 7: 1164 + 194 = 1358
Step 8: 1358 + 194 = 1552
Step 9: 1552 + 194 = 1746
Step 10: 1746 + 194 = 1940
Step 11: 1940 + 194 = 2134
Step 12: 2134 + 194 = 2328
Step 13: 2328 + 194 = 2522
Step 14: 2522 + 194 = 2716
Step 15: 2716 + 194 = 2910
Step 16: 2910 + 194 = 3104
Step 17: 3104 + 194 = 3298
Step 18: 3298 + 194 = 3492
Step 19: 3492 + 194 = 3686
Step 20: 3686 + 194 = 3880
Step 21: 3880 + 194 = 4074
Step 22: 4074 + 194 = 4268
Step 23: 4268 + 194 = 4462
Step 24: 4462 + 194 = 4656
Step 25: 4656 + 194 = 4850

So, 194*25 = 4850
