Using only 8's & 4's and using each atleast once...884. Using all numerals and including 8 once and 4 once...984.
Oh, what a happy little puzzle we have here! To get to 28 using only the numbers 2, 3, 4, and 5 once, we can add 5 and 4 together to get 9, then multiply that by 3 to get 27. Finally, we add 2 to reach 28. Just like painting a beautiful landscape, sometimes it's all about combining different elements to create something wonderful.
Assuming all of {7, 8, 2, 3} have to be used exactly once: (8 - 2) x (7 - 3) = 24.
What is 4 divided by 1,234
8 plus 1 , minus 5, plus 7 + 13
8736
8*9^(4/8) = 8*9^(1/2) which is 8*sqrt(9) = 8*3 = 24
Six.Six.Six.Six.
-- Photocopy the question or print the screen. -- Trim and discard the first 8.
One possible solution: 8 * 6 + average(5, 7)
(7 + 5 - 9) x 8 = 24
