Sure thing! We've got 818 and we're gonna multiply it by 7. That's the same as adding 818 to itself 7 times.
Step 1: 0 + 818 = 818
Step 2: 818 + 818 = 1636
Step 3: 1636 + 818 = 2454
Step 4: 2454 + 818 = 3272
Step 5: 3272 + 818 = 4090
Step 6: 4090 + 818 = 4908
Step 7: 4908 + 818 = 5726

So, 818*7 = 5726
