    Negative Sign & Degree Symbol?

    Two symbols I would like to use in LaTex:

    1) I've been using the minus sign if I want to type in negative numbers:
    y = -16
    but I don't like how big it is. Is there a way to type in a negative sign that's not as long and thick?

    2) How does one type the degree sign? I want to use the degree sign so that readers won't confuse the angle with radian measure, like this:
    \cos 60 = \frac{1}{2}
    When using the Character Map in Windows to copy and paste degree symbol, it doesn't appear. (I put a degree symbol in the above equation, so that you see what I mean.)

    TIA.

    EDIT: Question #2 withdrawn. I found out how to do it -- you can use ^\circ:
    \cos 60^\circ = \frac{1}{2}
    gives me this:
    \cos 60^\circ = \frac{1}{2}

    If I recall correctly, Soroban does this:

    y=\text{-}12 generates y=\text{-}12

    Does that help for now? There may be another way to do it...

    But the question is why?
    What is wrong with -3 over against \text{-}3?
    Frankly, I prefer the former.

    Long before I learned about [tex]30^{\circ}[/tex]: . 30^{\circ}

    . . I was using [tex]30^o[/tex]: . 30^o . . . much easier!



    I prefer the shorter minus signs in a variety of situations,
    . . but mostly in matrices.

    Compare . \left[\begin{array}{ccc|c}1 & -2 & 3 & -4 \\ -5 & 6 & -7 & 8\\ 9 &-10 & 11 & -12\end{array}\right] . and . \left[\begin{array}{ccc|c} 1 & \text{-}2 & 3 & \text{-}4\\ \text{-}5 & 6 & \text{-}7 & 8 \\ 9& \text{-}10 & 11 & \text{-}12 \end{array}\right]
