Alright, let's solve this math problem step by step. First, we have the number 570. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 28. So, we're going to take the number 570 and add it to itself 28 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
Step 23: 12540 + 570 = 13110
Step 24: 13110 + 570 = 13680
Step 25: 13680 + 570 = 14250
Step 26: 14250 + 570 = 14820
Step 27: 14820 + 570 = 15390
Step 28: 15390 + 570 = 15960

So, 570*28 = 15960
