Without delay, let's solve this. We've got 596 and we will be multiplying it by 18, that is, adding 596 to itself 18 times.
Step 1: 0 + 596 = 596
Step 2: 596 + 596 = 1192
Step 3: 1192 + 596 = 1788
Step 4: 1788 + 596 = 2384
Step 5: 2384 + 596 = 2980
Step 6: 2980 + 596 = 3576
Step 7: 3576 + 596 = 4172
Step 8: 4172 + 596 = 4768
Step 9: 4768 + 596 = 5364
Step 10: 5364 + 596 = 5960
Step 11: 5960 + 596 = 6556
Step 12: 6556 + 596 = 7152
Step 13: 7152 + 596 = 7748
Step 14: 7748 + 596 = 8344
Step 15: 8344 + 596 = 8940
Step 16: 8940 + 596 = 9536
Step 17: 9536 + 596 = 10132
Step 18: 10132 + 596 = 10728

So, 596*18 = 10728
