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

4 equivalent expressions for 28+500 

1. 528 - 28
2. 480 + 48
3. 490 + 38
4. 
470 + 58
