A solution to the four fours problem for the number 33 is: 33 = (4-.4)/.4+4!
(4x4) - (4/4)
11:55
44/4
4/4 + 4 × 4/4
((4 times 4) plus 4) divided by 4.
twenty-five
{4! - sqrt(4)}/.4
(4! - sqrt(4)) / .4 = (24-2)/.4 = 22/.4 = 55
You can make twenty-five using four fours with the following expression: ( 4 \times 4 + 4 + \frac{4}{4} ). Here, ( 4 \times 4 ) equals 16, then you add 4 to get 20, and finally, adding ( \frac{4}{4} ) (which is 1) gives you 25.
To make 11 using four fours, you can use the following equation: ( 4 \times 4 - 4 - 4 = 11 ). Here, you multiply two fours to get 16, then subtract two fours to reach 11. This creatively utilizes the four fours while adhering to the mathematical operations allowed.
