we know that
the number [tex]24[/tex] in words is equal to twenty-four
the number [tex]6[/tex] in words is equal to six
the number [tex]3[/tex] in words is equal to three
The symbol - in words is equal to minus
The symbol + in words is equal to plus
The symbol ( in words is equal to open parenthesis
The symbol ) in words is equal to close parenthesis
so
the expression is equal to twenty-four minus open parenthesis six plus three close parenthesis
therefore
the answer is
