Let's get this math done. We have 713 and we're going to multiply it by 9. This is the same as taking 713 and adding it to itself 9 times.
Step 1: 0 + 713 = 713
Step 2: 713 + 713 = 1426
Step 3: 1426 + 713 = 2139
Step 4: 2139 + 713 = 2852
Step 5: 2852 + 713 = 3565
Step 6: 3565 + 713 = 4278
Step 7: 4278 + 713 = 4991
Step 8: 4991 + 713 = 5704
Step 9: 5704 + 713 = 6417

So, 713*9 = 6417
