Problem: if the sum of two numbers is 12 and the sum of their squares is 124 , then the product of the numbers is
Rationale: "sol . let the numbers be x and y . then , ( x + y ) = 12 and x 2 + y 2 = 124 . now , 2 xy = ( x + y ) 2 - ( x 2 + y 2 ) = ( 12 ) 2 - 124 = 144 - 124 = 20 xy = 10 . answer a"
annotated_formula: divide(subtract(power(12, const_2), 124), const_2)
