    About black triangles, if someone wants to use \blacktriangleright or \blacktriangleleft just click on the image

    --

    Now watch

    \frac{2}{6} = \frac{2}{{2 \cdot 3}} = \frac{{\mathop {\rlap/2}\limits^1 }}{{\mathop {\rlap/2}\limits_1 \cdot 3}} = \frac{1}{3}.

    Really cool, isn't it? I made it with MathType. To generate the cross line, you gotta put {\rlap/}. See the code above.

    You actually had written this:

    Krizalid you so good at LaTeX that even those crazy Japanese people would be jealous of your skill
    I'm chilean!

    I like LaTeX, and I like help on it.

    I had made up this way to cancel fractions . . .

    . . \frac{\not4^2}{\not6_3} =\frac{2}{3} . . . \frac {\not4 ^2} {\not6 _3} = \frac{2}{3}


    But I really like your "rlap" code . . . it's looks much better!

    . . \frac{\rlap/4 ^2}{\rlap/6 _3} . . \frac{\rlap/4 ^2} { \rlap/6 _3}



    Let me try something: . frac{1{\rlap/9}} {{\rlap/9}5} = \frac{1}{5}

    . . \frac{1{\rlap/9}}{{\rlap/9}5} =\frac{1}{5} . . . . . Ha! It works!

    the thing is, i could not make the strike through go through two symbols, for instance, if you wanted to strike through (cancel) 19, you'd have to do one strike for the 1 and one for the 9. does anyone know how to go through two or more symbols at a time, or am i just being too picky?

    I was just browsing around and found some interesting information on this. I saw an example where x - x was canceled out by a diagonal line and had a 0 in the upper right corner.

    I couldn't find code for it, but the article mentioned using the "cancel package." So.......

    @MathGuru: Do we have the cancel package loaded into the site?

    I told him the same thing the last time, but looks like he didn't read it
