the unit digit in the product ( 293 * 567 * 917 * 343 ) is :
"explanation : unit digit in the given product = unit digit in ( 3 * 7 * 7 * 4 ) = 1 answer : b"
subtract(multiply(multiply(multiply(293, 567), 917), 343), subtract(multiply(multiply(multiply(293, 567), 917), 343), add(const_4, const_4)))
