Sure thing! We've got 417 and we're gonna multiply it by 7. That's the same as adding 417 to itself 7 times.
Step 1: 0 + 417 = 417
Step 2: 417 + 417 = 834
Step 3: 834 + 417 = 1251
Step 4: 1251 + 417 = 1668
Step 5: 1668 + 417 = 2085
Step 6: 2085 + 417 = 2502
Step 7: 2502 + 417 = 2919

So, 417*7 = 2919
