help with math plezzz!!!?

Question

i need help with my homework.......useing only four ,fours ....the answers must only go from 1-100 is the answers i need 100 of them? plezz help me out!!!!

EXAMPLE= 4+4-4+4=8 {u can only use four fours and who ever gives me the most answers i will give u the best answer!

Answer 1

Yet another asking of the classic "Four fours" problem...
4/4 * 4/4 = 1
√4 or 4/4 + 4/4 = 2
4 - 4/4 or (4+4+4)/4 = 3
4 or 4+4*(4-4) = 4
4 + √4 or 4*.4+4.4 (clever) =6
44/4 - 4 = 7
4 + 4 + (4-4) =8
4 + 4 + 4/4 = 9
44/4.4 = 10
44/4 = 11
...
4*4 -√4 =14
4*4 - 4/4 = 15
4*4 =16
4*4 + 4/4 = 17
4*4 +√4 =18
...
4*4*√4 = 32
...
4*4*4 = 64
...
44/.44 = 100

"here's a quick summary of the ``impurity'' levels. The ``zeroth'' level allows addition (+), subtraction/negation (-), multiplication (*), division (/), square root (sqrt), factorial (!), and power (^). Parentheses may be used for grouping. The digit 4 must be used exactly four times, and the decimal digit (.) can be used. The higher impurity levels are:

2: The overline, an infinitely repeated digit (shown as ~ in ASCII text).
3: An arbitrary root power.
4: The gamma function; gamma(x) = (x-1)!.
5: %.
6: The square function.
7: logical-or, exclusive-or, and logical-and.
8: logical left shift and right shift.
I always choose the solution with the smallest impurity, then the fewest number of operations with that impurity."

Answer 2

Exactly four 4s, or not more than four 4s?

1 = 4/4 + (4-4) = (4!*4!)/(4!*4!) = 44/44 = (4*4)/(4*4) = 4/4 * 4/4
2 = 4/4 + 4/4
3 = (4+4+4)/4
4 = 4 + (4-4)^4
5 = 4 + (4/4)^4
6 = 4!/4 * (4/4)
7 = 4 + 4 - 4/4
8 = 4+4+4-4 = (4+4)(4/4)
9 = 4+4 + 4/4
10 = 4!/4 + 4
11 = 44/4
12 = 4!*4/(4+4)
