    Using five 2s and as many plus symbols as you need, make an equation that equals 28

    Answer:
    22 + 2 + 2 + 2 = 28


    Another one, now that you see how they work.

    Using eight 8s and as many plus symbols as you need, make an equation that equals 1000

    Answer:
    888 + 88 + 8 + 8 + 8 = 1000

    Yeah, It's a hard puzzle to explain. That's why I posted two. The first one's more of an example and the second is more difficult.
