Question 1. State whether True or False. Provide a reason in each case. a. The pair (No, +) consisting of the set of whole numbers No = NU {0}, together with the operation of addition +, constitutes a monoid. b. The pair (E,-) consisting of the set of even integers & = {2n: ne Z}, together with the operation of addition +, constitutes a group. c. Given the set As = {r: 2 is a letter of the Latin alphabet}, together with some binary operation : As x As → Ag. The number of magmas that can be defined in this way is equal to 26676 exactly.
