    multiply \(\rm \color{green}{top}\) of first fraction by the \(\rm \color{red}{bottom}\) of the 2nd fraction and multiply bottom of the first fraction by the top of 2nd fraction

    |dw:1433535053525:dw| distribute: multiply everything which is inside the parentheses by outside term so 8(k+3) = 8 times k + 8 times 3
