Sure thing! We've got 411 and we're gonna multiply it by 11. That's the same as adding 411 to itself 11 times.
Step 1: 0 + 411 = 411
Step 2: 411 + 411 = 822
Step 3: 822 + 411 = 1233
Step 4: 1233 + 411 = 1644
Step 5: 1644 + 411 = 2055
Step 6: 2055 + 411 = 2466
Step 7: 2466 + 411 = 2877
Step 8: 2877 + 411 = 3288
Step 9: 3288 + 411 = 3699
Step 10: 3699 + 411 = 4110
Step 11: 4110 + 411 = 4521

So, 411*11 = 4521
