   1. +
   2. 7
   3. 3
   4. add
   5. ++

2. What is an operand?

   2. A symbol that performs an operation
   3. The final computed result of an expression
   4. A punctuation mark used to end a statement

3. Operator precedence example

   Given the expression x = 2 * 5 + 1, which part is evaluated first according to standard operator precedence rules?

   1. 2 * 5
   2. x = 2
   3. 5 + 1
   4. x = (2 * 5) + 1
   5. 2 * (5 + 1)

4. Unary vs binary

   Which of the following is an example of a unary operator applied to a single operand?

   1. -n
   2. a - b
   3. x / y
   4. p + q + r
   5. n-

5. Parentheses influence

   In the expression (2 + 3) * 4, which part is evaluated first and why?

   1. 2 + 3 because parentheses override normal precedence
   2. 3 * 4 because multiplication has the highest precedence
   3. 2 * 3 because expressions are read strictly left to right
   4. 2 + (3 * 4) because addition always happens before multiplication
   5. 2 + 3 * 4 because parentheses are optional
