It's hard to represent this with only the characters on the keyboard, so I'll have to explain it as best I can.
Using bar notation to denote an infinitely repeating decimal, 0.4444444... can be represented as .4 with a bar over the 4. The best I can do here is to put a line through the four: .4 If you were writing it by hand, the line would be on top of the four, not through it.
Then 4/.4 = 9. The square root of 9 is 3, and 34 = 81. 81 - 4 = 77, so we have:
sqrt(4/.4)4 - 4 = 77
Substitute the square root symbol for "sqrt()"
There are six fours in twenty-four.
44 / 4 + root(4) is one solution. You can find additional solutions in the Wikipedia article "Four fours".
4+4(4-4)
16, 44, or 8
(4+4)/4 + 4
23
To achieve the number 77 with four fours, the solution is as follows: sqrt(4/.4)4 - 4 Instead of the second four being equal to four tenths, place a dot over the top to indicate it being equal to four ninths.
There are 77 eighty-fours in 672
There are six fours in twenty-four.
four fours equals 24 not 23. or if u meant four 4ths, then it's 256.
The plural form of four is fours

A solution to the four fours problem for the number 33 is: 33 = (4-.4)/.4+4!
44 / 4 + root(4) is one solution. You can find additional solutions in the Wikipedia article "Four fours".
