Sure thing! We've got 562 and we're gonna multiply it by 20. That's the same as adding 562 to itself 20 times.
Step 1: 0 + 562 = 562
Step 2: 562 + 562 = 1124
Step 3: 1124 + 562 = 1686
Step 4: 1686 + 562 = 2248
Step 5: 2248 + 562 = 2810
Step 6: 2810 + 562 = 3372
Step 7: 3372 + 562 = 3934
Step 8: 3934 + 562 = 4496
Step 9: 4496 + 562 = 5058
Step 10: 5058 + 562 = 5620
Step 11: 5620 + 562 = 6182
Step 12: 6182 + 562 = 6744
Step 13: 6744 + 562 = 7306
Step 14: 7306 + 562 = 7868
Step 15: 7868 + 562 = 8430
Step 16: 8430 + 562 = 8992
Step 17: 8992 + 562 = 9554
Step 18: 9554 + 562 = 10116
Step 19: 10116 + 562 = 10678
Step 20: 10678 + 562 = 11240

So, 562*20 = 11240
