Q2.2.2 The operators listed in Table 2.1 are all binary operators: they take two operands (numbers) and return a single value. The symbol - is also used as a unary 2.2 Numbers, Variables, Comparisons and Logic 25 operator, which returns the negative value of the single operand on which it acts. For example, > a=4 >b=a b 4 Note that the expression b=a (which sets the variable b to the negative value of a ) is different from the expression b=a (which subtracts a from b and stores the result in b). The unary - operator has a higher precedence than *, / and % but a lower precedence than exponentiation (), so that, for example 24 is 16 (i.e. (24),not(2)4). Predict the result of the following expressions and check them using the Python shell.
