    in math, a number in parenthesis is multiplied. So this would be 19*24 = 19*20 + 19*4 Which is true and the rational behind the distributive property of multiplication.

    The equation is true, but that could have been trivially confirmed with a calculator.

    I don't understand what you mean. a*(b+c) = a*b + a*c by the distributive rule of multiplication

    I wrote the general form for the principle you were asking about. Just substitute a, b, and c for whatever numbers you like.

    e.g. a=2, b=3, c=4 2*(3+4) = 2*7 = 14 2*3 + 2*4 = 6 + 8 = 14
