    DAT Math: Pentose and Hexose Permutation Problem | DAT Destroyer | OAT Destroyer | Dr. Jim Romano

    Permutation problems reward students who identify the restriction before they begin counting. In this example, a sequence consists of three pentoses (5-carbon sugars) and five hexoses (6-carbon sugars), with the condition that a hexose must be placed on each end. Once those positions are...
