4 times 4 minus 4 minus square root of 4.
(4 x 4) - (4 + SQROOT(4))
(44 - 4)/4 x 4/4
44 / 4 + root(4) is one solution. You can find additional solutions in the Wikipedia article "Four fours".
a rhombus has four sides that are congruent
There are four 4's in a standard deck of cards.
(44 - 4)/4 = 40/4 = 10
4-4*4+4=4
There are several ways of making 10 using four fours. Amongst them are the following: (44 - 4)/4 = 10 44 / 4.4 = 10 4 + sqrt(4) + sqrt(4) + sqrt(4) = 10
4+4(4-4)
(4x4)-(4+4sqr) (4x4)=16 (4+4sqr)=6 16-6=10

Using four fours, you can get 19 with the following sum: 4! - 4 - (4 / 4) That is, four factorial minus four - (four divided by four) - 24 - 4 - (4 / 4) = 19
44 + 4/4
