OK, let's work through this together. We're starting with 753 and we're going to multiply it by 13, which means we add 753 to itself 13 times.
Step 1: 0 + 753 = 753
Step 2: 753 + 753 = 1506
Step 3: 1506 + 753 = 2259
Step 4: 2259 + 753 = 3012
Step 5: 3012 + 753 = 3765
Step 6: 3765 + 753 = 4518
Step 7: 4518 + 753 = 5271
Step 8: 5271 + 753 = 6024
Step 9: 6024 + 753 = 6777
Step 10: 6777 + 753 = 7530
Step 11: 7530 + 753 = 8283
Step 12: 8283 + 753 = 9036
Step 13: 9036 + 753 = 9789

So, 753*13 = 9789
