28 + 500 = 528, so just make 4 expressions with the answer of 528 for each
1. 21 + 507
2. 1 + 527
3. (4 x 7) + 500
4. 530 - 2
There are a whole lot more ways, so you can change these if you want. (It's really super simple.) Hope this helped

28 + 500 = 528
528 - 28 = 500
28 + 500 = 528 - 28
500 - 10 = 490
28 + 10 = 38
490 + 38 = 28 + 500
500 - 20 = 480
480 + 48 = 28 + 500
500 - 30 = 470
470 + 58 = 28 + 500
