    when adding or subtracting fractions, we need the lowest common denominator


    <br />
\frac{1+x}{3} + \frac{x-5}{6}<br />

    <br />
\frac{2 + 2x + x - 5}{6}<br />

    <br />
\frac{3x - 3}{6}<br />

    <br />
\frac{x -1}{2}<br />

    Please use brackets so that we know what you mean.

    Is a supposed to be:

    1+\frac{x}{3} + x-\frac{5}{6}

    or:

    \frac{(1+x)}{3} + \frac{(x-5)}{6}?
