Four 4's

[PkmnQ]

Basically, you have four 4's, and you need to do math with them to get to your post ID. Here are the standard allowed operations:

m + n (Addition)
m - n (Subtraction)
-n (Negation)
m * n (Multiplication)
m / n (Division)
m ^ n (Exponentiation)
sqrt(n) (Square root)
n! (Factorial)

You are also allowed to do things like 44, .4, 4.4, etc. You're even allowed to use .4̅ (or .(4) for a more ASCII-friendly representation). But they take the same amount of 4's as their representation.

However, to mix things up, here are some extra operations:

m ^^ n (Tetration)
!n (Subfactorial)
m % n (Modulo)

Here are some easy examples:

Code Select Expand

4 + 4 + 4 + 4 = 16
(4 + 4 + 4) * 4 = 48
sqrt((4 - 4 - 4)/4) = i
(4 - 4) / (4 - 4) = indeterminateAnd here are some less easy examples:

Code Select Expand

(!!4 % 44) / 4 = 30
(!(4!) % (4! ^ !4)) % !!4 = 103705
!44 % !(4 * 4) = 5846821604119Now I could go with the easy way, but I'll do this instead:
((4 ^ 4) % !4) / 4 = (256 % 9) / 4 = 4 / 4 = 1

(4/4)+(4/4) = 2

[PkmnQ]

(!4 + !4 + !4) % 4 = 3

Hey I actually had a book where I do this

(4! - 4 * 4) / sqrt(4) = 4

[Gilbert189]

44 % 4 + 4 = 4
(ninja aaaa)
4! / 4 - (4 / 4) = 5

[Byron_Inc_TBG]

4 / sqrt(4) + sqrt(4) + sqrt(4) = 6

[Gilbert189]

44 / 4 - 4 = 7

[Byron_Inc_TBG]

4 + 4 + 4 - 4 = 8

[the2000]

4 + 4 + 4 / 4

[Gilbert189]

(44 - 4) / 4

[PkmnQ]

(44 / 4) * !sqrt(4)

[Gilbert189]

(4 + 44) / 4

[PkmnQ]

!4 + 4 + (4 - 4)

[Gilbert189]

(4! / 4) + 4 + 4

[CST1229]

4 * 4 - (4 / 4)

[redgreenandblue]

4*4*(4/4)

[PkmnQ]

!sqrt(4) + sqrt(!4) + !4 + 4

[Byron_Inc_TBG]

4 × 4 + 4 / sqrt(4)

[the2000]

4! - 4 - 4 / 4

[CST1229]

4*4+sqrt(4)+sqrt(4)

[PkmnQ]

sqrt(!4) * (!4 - !sqrt(4) - !sqrt(4))

[solitaire]

4 x 4 + 4 + sqrt(4)

[Gilbert189]

4! - sqrt(4) ^ sqrt(4) / 4

[PkmnQ]

4! + (4 * (4 - 4))

[Byron_Inc_TBG]

(4 + (4 / 4)) ^ sqrt(4)

OR

4! + (4 / sqrt(4)) / sqrt(4)
