Let's roll up our sleeves and solve this. We have 734 and we're going to multiply it by 25, essentially adding 734 to itself 25 times.
Step 1: 0 + 734 = 734
Step 2: 734 + 734 = 1468
Step 3: 1468 + 734 = 2202
Step 4: 2202 + 734 = 2936
Step 5: 2936 + 734 = 3670
Step 6: 3670 + 734 = 4404
Step 7: 4404 + 734 = 5138
Step 8: 5138 + 734 = 5872
Step 9: 5872 + 734 = 6606
Step 10: 6606 + 734 = 7340
Step 11: 7340 + 734 = 8074
Step 12: 8074 + 734 = 8808
Step 13: 8808 + 734 = 9542
Step 14: 9542 + 734 = 10276
Step 15: 10276 + 734 = 11010
Step 16: 11010 + 734 = 11744
Step 17: 11744 + 734 = 12478
Step 18: 12478 + 734 = 13212
Step 19: 13212 + 734 = 13946
Step 20: 13946 + 734 = 14680
Step 21: 14680 + 734 = 15414
Step 22: 15414 + 734 = 16148
Step 23: 16148 + 734 = 16882
Step 24: 16882 + 734 = 17616
Step 25: 17616 + 734 = 18350

So, 734*25 = 18350
