Let's roll up our sleeves and solve this. We have 570 and we're going to multiply it by 22, essentially adding 570 to itself 22 times.
Step 1: 0 + 570 = 570
Step 2: 570 + 570 = 1140
Step 3: 1140 + 570 = 1710
Step 4: 1710 + 570 = 2280
Step 5: 2280 + 570 = 2850
Step 6: 2850 + 570 = 3420
Step 7: 3420 + 570 = 3990
Step 8: 3990 + 570 = 4560
Step 9: 4560 + 570 = 5130
Step 10: 5130 + 570 = 5700
Step 11: 5700 + 570 = 6270
Step 12: 6270 + 570 = 6840
Step 13: 6840 + 570 = 7410
Step 14: 7410 + 570 = 7980
Step 15: 7980 + 570 = 8550
Step 16: 8550 + 570 = 9120
Step 17: 9120 + 570 = 9690
Step 18: 9690 + 570 = 10260
Step 19: 10260 + 570 = 10830
Step 20: 10830 + 570 = 11400
Step 21: 11400 + 570 = 11970
Step 22: 11970 + 570 = 12540

So, 570*22 = 12540
