OK, let's crack this. We're given 568 and our task is to multiply it by 13. Essentially, we'll be adding 568 to itself 13 times.
Step 1: 0 + 568 = 568
Step 2: 568 + 568 = 1136
Step 3: 1136 + 568 = 1704
Step 4: 1704 + 568 = 2272
Step 5: 2272 + 568 = 2840
Step 6: 2840 + 568 = 3408
Step 7: 3408 + 568 = 3976
Step 8: 3976 + 568 = 4544
Step 9: 4544 + 568 = 5112
Step 10: 5112 + 568 = 5680
Step 11: 5680 + 568 = 6248
Step 12: 6248 + 568 = 6816
Step 13: 6816 + 568 = 7384

So, 568*13 = 7384
