Without delay, let's solve this. We've got 734 and we will be multiplying it by 10, that is, adding 734 to itself 10 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

So, 734*10 = 7340
