4+4=8
4*4!/(4+4) = 4*24/8 = 12
To get 7 using only 4 fours, you can use the following mathematical expression: (4 + 4) / (4 / 4) = 8 / 1 = 8. Then subtract 1 from 8 to get 7. This solution involves basic arithmetic operations and the constraint of using only four instances of the number four.
To get 44 using 4 fours, you can use the following mathematical expression: (4! + 4) + (4/4) = 44. In this equation, the factorial symbol (!) represents the product of all positive integers up to that number. So, 4! = 4 x 3 x 2 x 1 = 24. Adding 4 to 24 gives you 28. Dividing 4 by 4 equals 1. Adding 28 and 1 together equals 29. Finally, 29 + 15 = 44.
(4!/4)4 - 4
4+4(4-4)
4*4*4-(4/4)
(4x4+4)/4
(4+4)/4 + 4 = 6 break-down: (4 + 4)/4 = 8/4 = 2 2 + 4 = 6
4/4+4/4=2
4! + [(4*4)/4^2]
4 + 4 - (4/4) = 7
