Sure thing! We've got 219 and we're gonna multiply it by 20. That's the same as adding 219 to itself 20 times.
Step 1: 0 + 219 = 219
Step 2: 219 + 219 = 438
Step 3: 438 + 219 = 657
Step 4: 657 + 219 = 876
Step 5: 876 + 219 = 1095
Step 6: 1095 + 219 = 1314
Step 7: 1314 + 219 = 1533
Step 8: 1533 + 219 = 1752
Step 9: 1752 + 219 = 1971
Step 10: 1971 + 219 = 2190
Step 11: 2190 + 219 = 2409
Step 12: 2409 + 219 = 2628
Step 13: 2628 + 219 = 2847
Step 14: 2847 + 219 = 3066
Step 15: 3066 + 219 = 3285
Step 16: 3285 + 219 = 3504
Step 17: 3504 + 219 = 3723
Step 18: 3723 + 219 = 3942
Step 19: 3942 + 219 = 4161
Step 20: 4161 + 219 = 4380

So, 219*20 = 4380
