OK, let's work through this together. We're starting with 662 and we're going to multiply it by 11, which means we add 662 to itself 11 times.
Step 1: 0 + 662 = 662
Step 2: 662 + 662 = 1324
Step 3: 1324 + 662 = 1986
Step 4: 1986 + 662 = 2648
Step 5: 2648 + 662 = 3310
Step 6: 3310 + 662 = 3972
Step 7: 3972 + 662 = 4634
Step 8: 4634 + 662 = 5296
Step 9: 5296 + 662 = 5958
Step 10: 5958 + 662 = 6620
Step 11: 6620 + 662 = 7282

So, 662*11 = 7282
