Problem: how many internal diagonals does a pentagon ( five sided polygon ) have ?
Rationale: "number of diagonals in any polygon can be found using this formula : n ( n - 3 ) / 2 here n = 5 no . of diagonals = 5 ( 5 - 3 ) / 2 = 5 ans a"
annotated_formula: multiply(subtract(multiply(const_2, const_4), const_3), divide(multiply(const_2, const_4), const_2))
