3. Considering the operator definition: You are given the following operators: +(int, int) int (plus) -(int, int) int (minus) &&(boolean, boolean) → boolean (and) ||(boolean, boolean) → boolean (or) == (int, int)→ boolean (equality) == (boolean, boolean)→ boolean (equality) . . name(input1_type, input2.type,...) → output_type . Note: Operator: +(int, int)→int, means it takes two integers, performs an add operation on them, and outputs an integer. Using the given operators, decide whether the following expressions ((a) to (e)) are typeable or not. If the expression is typeable (able to be reduced to a typed expression), give its type. and expected output. Otherwise, give an explanation of why it is not typeable. (a) True (b) 10+3 (c) 6-2.1 (d) (2-1) True (e) (4+5) -- (1+7)
