(4/.4)+4+4 or (44x.4)+.4
4 - (4/4 x 4/4) or 4 + 4 - 4 - 4/4
To make 18 using 4 fours, you can use the following mathematical expression: (4 + 4) x (4 - 4) = 8 x 0 = 0. This equation combines addition, multiplication, and subtraction to reach the desired result of 0.
(4x4+4) / 4=5
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! - sqrt(4)}/.4
4/4 + 4 × 4/4
4*(4! + 4/4)
(4!/4)4 - 4
4+4(4-4)
4*4+4/4 = 17
4*4*4-(4/4)
