Without delay, let's solve this. We've got 595 and we will be multiplying it by 13, that is, adding 595 to itself 13 times.
Step 1: 0 + 595 = 595
Step 2: 595 + 595 = 1190
Step 3: 1190 + 595 = 1785
Step 4: 1785 + 595 = 2380
Step 5: 2380 + 595 = 2975
Step 6: 2975 + 595 = 3570
Step 7: 3570 + 595 = 4165
Step 8: 4165 + 595 = 4760
Step 9: 4760 + 595 = 5355
Step 10: 5355 + 595 = 5950
Step 11: 5950 + 595 = 6545
Step 12: 6545 + 595 = 7140
Step 13: 7140 + 595 = 7735

So, 595*13 = 7735
