Alright, let's solve this math problem step by step. First, we have the number 219. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 20. So, we're going to take the number 219 and add it 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
