How many ways can you find to make exactly 1000 with eight eights? You can only add, subtract, multiply, divide, use exponents and parentheses, and you can't use any number except 8.

Here are two relatively straightforward solutions.... not sure if they've been posted before

1) (8888-888)/8

 

2) ((8/8)+(8/8))^8 - (8+8+8)
