Let's get this math done. We have 702 and we're going to multiply it by 13. This is the same as taking 702 and adding it to itself 13 times.
Step 1: 0 + 702 = 702
Step 2: 702 + 702 = 1404
Step 3: 1404 + 702 = 2106
Step 4: 2106 + 702 = 2808
Step 5: 2808 + 702 = 3510
Step 6: 3510 + 702 = 4212
Step 7: 4212 + 702 = 4914
Step 8: 4914 + 702 = 5616
Step 9: 5616 + 702 = 6318
Step 10: 6318 + 702 = 7020
Step 11: 7020 + 702 = 7722
Step 12: 7722 + 702 = 8424
Step 13: 8424 + 702 = 9126

So, 702*13 = 9126
