Without delay, let's solve this. We've got 730 and we will be multiplying it by 9, that is, adding 730 to itself 9 times.
Step 1: 0 + 730 = 730
Step 2: 730 + 730 = 1460
Step 3: 1460 + 730 = 2190
Step 4: 2190 + 730 = 2920
Step 5: 2920 + 730 = 3650
Step 6: 3650 + 730 = 4380
Step 7: 4380 + 730 = 5110
Step 8: 5110 + 730 = 5840
Step 9: 5840 + 730 = 6570

So, 730*9 = 6570
