    Best answer

    4 * 4 - SQRT(4) - SQRT (4) = 12

    4 * 4 - 4 + SQRT(4) = 14

    Isn't it time to start doing these on your own?

    4*4-4=12

    lol.. 4+4+4-4=12, not 8.. so that is how you get twelve, eiht is 4x4-4-4, 14 is impossible with using 4, 4 times.

    do you have to use it 4 times? or can you not exceed 4 times?

    4x4-4=12

    i don't know how to get to 14

    Twelve is easy.... 4 + 4 + 4

    14 is a little trickier but just as easy.

    (4+4+4+4) - 4 x (4/(4+4))

    (44+4)/4=12

    ((44-4)/4)+4=14

    for 12: 4+4+4 or (4x4)-4+4

    for 14: (4x4)-4+sqrt(4)

    yeah, that should be about right. =]

    Source(s): did that is 7th grade. =]

    4x(4-(4/4))=4x(4-1)=4x3=12

    4x4-((4+4)/4)=16-(8/4)=16-2=14

    I don't know if it will help u though cuz it's using 4, 5 times

    (4-(4/4))*4= 12

    14 i cant think of right now.
