OK, let's work through this together. We're starting with 976 and we're going to multiply it by 28, which means we add 976 to itself 28 times.
Step 1: 0 + 976 = 976
Step 2: 976 + 976 = 1952
Step 3: 1952 + 976 = 2928
Step 4: 2928 + 976 = 3904
Step 5: 3904 + 976 = 4880
Step 6: 4880 + 976 = 5856
Step 7: 5856 + 976 = 6832
Step 8: 6832 + 976 = 7808
Step 9: 7808 + 976 = 8784
Step 10: 8784 + 976 = 9760
Step 11: 9760 + 976 = 10736
Step 12: 10736 + 976 = 11712
Step 13: 11712 + 976 = 12688
Step 14: 12688 + 976 = 13664
Step 15: 13664 + 976 = 14640
Step 16: 14640 + 976 = 15616
Step 17: 15616 + 976 = 16592
Step 18: 16592 + 976 = 17568
Step 19: 17568 + 976 = 18544
Step 20: 18544 + 976 = 19520
Step 21: 19520 + 976 = 20496
Step 22: 20496 + 976 = 21472
Step 23: 21472 + 976 = 22448
Step 24: 22448 + 976 = 23424
Step 25: 23424 + 976 = 24400
Step 26: 24400 + 976 = 25376
Step 27: 25376 + 976 = 26352
Step 28: 26352 + 976 = 27328

So, 976*28 = 27328
