Without delay, let's solve this. We've got 569 and we will be multiplying it by 28, that is, adding 569 to itself 28 times.
Step 1: 0 + 569 = 569
Step 2: 569 + 569 = 1138
Step 3: 1138 + 569 = 1707
Step 4: 1707 + 569 = 2276
Step 5: 2276 + 569 = 2845
Step 6: 2845 + 569 = 3414
Step 7: 3414 + 569 = 3983
Step 8: 3983 + 569 = 4552
Step 9: 4552 + 569 = 5121
Step 10: 5121 + 569 = 5690
Step 11: 5690 + 569 = 6259
Step 12: 6259 + 569 = 6828
Step 13: 6828 + 569 = 7397
Step 14: 7397 + 569 = 7966
Step 15: 7966 + 569 = 8535
Step 16: 8535 + 569 = 9104
Step 17: 9104 + 569 = 9673
Step 18: 9673 + 569 = 10242
Step 19: 10242 + 569 = 10811
Step 20: 10811 + 569 = 11380
Step 21: 11380 + 569 = 11949
Step 22: 11949 + 569 = 12518
Step 23: 12518 + 569 = 13087
Step 24: 13087 + 569 = 13656
Step 25: 13656 + 569 = 14225
Step 26: 14225 + 569 = 14794
Step 27: 14794 + 569 = 15363
Step 28: 15363 + 569 = 15932

So, 569*28 = 15932
