Let's get this math done. We have 735 and we're going to multiply it by 10. This is the same as taking 735 and adding it to itself 10 times.
Step 1: 0 + 735 = 735
Step 2: 735 + 735 = 1470
Step 3: 1470 + 735 = 2205
Step 4: 2205 + 735 = 2940
Step 5: 2940 + 735 = 3675
Step 6: 3675 + 735 = 4410
Step 7: 4410 + 735 = 5145
Step 8: 5145 + 735 = 5880
Step 9: 5880 + 735 = 6615
Step 10: 6615 + 735 = 7350

So, 735*10 = 7350
