OK, let's work through this together. We're starting with 929 and we're going to multiply it by 28, which means we add 929 to itself 28 times.
Step 1: 0 + 929 = 929
Step 2: 929 + 929 = 1858
Step 3: 1858 + 929 = 2787
Step 4: 2787 + 929 = 3716
Step 5: 3716 + 929 = 4645
Step 6: 4645 + 929 = 5574
Step 7: 5574 + 929 = 6503
Step 8: 6503 + 929 = 7432
Step 9: 7432 + 929 = 8361
Step 10: 8361 + 929 = 9290
Step 11: 9290 + 929 = 10219
Step 12: 10219 + 929 = 11148
Step 13: 11148 + 929 = 12077
Step 14: 12077 + 929 = 13006
Step 15: 13006 + 929 = 13935
Step 16: 13935 + 929 = 14864
Step 17: 14864 + 929 = 15793
Step 18: 15793 + 929 = 16722
Step 19: 16722 + 929 = 17651
Step 20: 17651 + 929 = 18580
Step 21: 18580 + 929 = 19509
Step 22: 19509 + 929 = 20438
Step 23: 20438 + 929 = 21367
Step 24: 21367 + 929 = 22296
Step 25: 22296 + 929 = 23225
Step 26: 23225 + 929 = 24154
Step 27: 24154 + 929 = 25083
Step 28: 25083 + 929 = 26012

So, 929*28 = 26012
