    The distributive property states that:

    a (b+c) = ab+bc.

    or more generally: a (b+c+d) = ab+av+ad.

    This is a very useful tool to perform multiplication.

    For example, if we want to multiply 7 by 234, we can proceed as follows:

    7*234=7 (200+30+4) = 7*200+7*30+7*4=1400+210+28=1610+28=1638

    back to our problem,

    4 * 24 = 4 (20+4) = 4*20+4*4=80+16=96 ($)

    So, instead of multiplying 4 by 24, we multiplied 4 by 20 and 4, which is easier, and then added these together.

    Answer:

    4 * 24 = 4 (20+4) [=4*20+4*4=80+16=96 ($) ]
