    Math Riddle/Brain Teaser?

    So, I have to use the numbers 2, 3, 4, and 6 to make the number 86. The rules are this:
    -You can use any operation
    -You can use parentheses
    -You can use any function on a calculator
    -This includes factorials, exponents, or square roots
    -You have to use all numbers and not reuse them more than once

    -You cannot group numbers together (ie, 2 and 3 does not equal 23

    Please, I would appreciate it if someone helped! This has taken me over an hour ):

    86 = (6 / .2) x 3 - 4

    EDIT: So what's the back story here? Another user asked the same question then deleted it after I answered

    I think it's one of those "read the question thoroughly" riddles. Hate those ones.

    Anyway, here's one of an infinte amount of answers.

    2+3+4+6+(71)!=86.

    One will see by reading the intructions that adding new numbers is permissable.





    PPPPPWWWWWWWWNNNNNNNNNEEEDDDDDDDD




    EDIT: To Paula 124: 0.2 is not 2. Thankyou, goodbye.
