Let's get this math done. We have 60 and we're going to multiply it by 11. This is the same as taking 60 and adding it to itself 11 times.
Step 1: 0 + 60 = 60
Step 2: 60 + 60 = 120
Step 3: 120 + 60 = 180
Step 4: 180 + 60 = 240
Step 5: 240 + 60 = 300
Step 6: 300 + 60 = 360
Step 7: 360 + 60 = 420
Step 8: 420 + 60 = 480
Step 9: 480 + 60 = 540
Step 10: 540 + 60 = 600
Step 11: 600 + 60 = 660

So, 60*11 = 660
