A Game of Four - HARDCORE MATH

[Cybertails1998]

4 X (4⁴ - 4) - 4 X sqrt(4) = 1000

edit: wait hold on you actually have to coordinate the answers? ...yeah I got nothing sorry

44/4 - log₄(4*4) = 13
that violates the rules but I got the basic concept of calculating 13

I might program a routine that calculates the numbers.

[.:FancyPants:.]

pffft you can't use logs

log₄4 = 1
log₄(4 * 4) = 2
log₄(4 * 4 * 4) = 3

Coincidentally, I had already made a program to exhaustively search all possible combinations. Assuming the only valid operators are +, -, *, /, ^, and @ (concatenates two fours, so 44 = 4 @ 4), and that there's a maximum of four fours:

EDIT: Alternatively, disallowing exponentiation, we get:
