    Here is a possibility, but try to find by yourself if there's another one >.<

    7*4+5+11=44.

    Ummm that equals 16, not 44. You would need parentheses to make that work..

    (7 + 4) x 5 - 11 = 44

    You KNOW I can't resist, right?

    A = 4
    B = 5
    C = 7
    D = 11

    D+(B+(C*A)) (D+B)+(A*C) (D+(C*A))+B (D*B)-(C+A) (C*(D-A))-B
    B+(D+(C*A)) (B+D)+(A*C) (D+(A*C))+B (B*D)-(C+A) ((D*B)-C)-A
    D+(B+(A*C)) (C*A)+(B+D) (B+(C*A))+D (D*B)-(A+C) ((B*D)-C)-A
    B+(D+(A*C)) (A*C)+(B+D) (B+(A*C))+D (B*D)-(A+C) ((D-A)*C)-B
    (D+B)+(C*A) D+((C*A)+B) ((C*A)+D)+B (B*(C+A))-D ((D*B)-A)-C
    (B+D)+(C*A) D+((A*C)+B) ((A*C)+D)+B (B*(A+C))-D ((B*D)-A)-C
    (C*A)+(D+B) B+((C*A)+D) ((C*A)+B)+D ((C+A)*B)-D
    (A*C)+(D+B) B+((A*C)+D) ((A*C)+B)+D ((A+C)*B)-D

    There are 38 ways to do it using the Standard 24-Challenge rules.
