Sure thing! We've got 517 and we're gonna multiply it by 7. That's the same as adding 517 to itself 7 times.
Step 1: 0 + 517 = 517
Step 2: 517 + 517 = 1034
Step 3: 1034 + 517 = 1551
Step 4: 1551 + 517 = 2068
Step 5: 2068 + 517 = 2585
Step 6: 2585 + 517 = 3102
Step 7: 3102 + 517 = 3619

So, 517*7 = 3619
