OK, let's crack this. We're given 570 and our task is to multiply it by 11. Essentially, we'll be adding 570 to itself 11 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

So, 570*11 = 6270
