4444 + 444 + 44 + 44 + (4 x 4) + 4 + 4 +4 = 5004
4444 + 444 + 44 + 44 + 44 - 4 - ( 4 x 4 ) = 5000
That's cheating. He said using only the number 4, not the numeral 4. Here's what I came up with:

((4/4) + (4/4) + (4/4) + 4 + 4(4+4)) x 4 x 4 x (4+4) + 4 + 4 =
(1 + 1 + 1 + 4 + 4(8)) x 16 x 8 + 8 =
(7 + 32) x 128 + 8 =
39 x 128 + 8 =
4992 + 8 =
5000

My son is very happy. He got to stay up late AND has the solution! Thank you.  Smiley  Cheesy  Smiley

I've put my math team on it, they did 8th grade twice IIRC, so naturally they should have an advantage.

Thank you!

4444 + 444 + 44 + 44 + (4 x 4) + 4 + 4 + 4 = 5004    Cheesy

My son was asked to use the number 4 in a math problem 16 times so that the result equals 5000.

So far the closest we've gotten is 5004.

The problem can only contains 4's.
