find the last digit in the product 287 x 287 + 269 x 269 - 2 x 287 x 269 ?
explanation : given exp . = a 2 + b 2 - 2 ab , where a = 287 and b = 269 = ( a - b ) 2 = ( 287 - 269 ) 2 = ( 182 ) = 324 answer is e
subtract(subtract(add(multiply(287, 287), multiply(269, 269)), multiply(multiply(2, 287), 269)), add(multiply(const_10, const_2), multiply(const_3, const_100)))
