8.    On the last page, absolute value and square root were written using abs(argument) and sqrt(argument) so that the idea could be typewritten on one line without special math symbols. Please simplify the expression written using this code used by calculators, computers, and web pages. NOTE: The symbol * is used to indicate multiplication. The / symbol indicates division.
5 + 4 * ( sqrt((10+3)*(16-3) - 12/2*2*12)/10 + abs(3 - 1/2))
