OK, let's work through this together. We're starting with 568 and we're going to multiply it by 26, which means we add 568 to itself 26 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
Step 14: 7384 + 568 = 7952
Step 15: 7952 + 568 = 8520
Step 16: 8520 + 568 = 9088
Step 17: 9088 + 568 = 9656
Step 18: 9656 + 568 = 10224
Step 19: 10224 + 568 = 10792
Step 20: 10792 + 568 = 11360
Step 21: 11360 + 568 = 11928
Step 22: 11928 + 568 = 12496
Step 23: 12496 + 568 = 13064
Step 24: 13064 + 568 = 13632
Step 25: 13632 + 568 = 14200
Step 26: 14200 + 568 = 14768

So, 568*26 = 14768
