3) Integer division is when you divide two ints and the result gets rounded up. (F)

4) An operator is allowed to have different meanings depending on its operands. (T)

5) An arithmetic expression is anything that evaluates to a number. (T)

6) You can automatically convert from int to short, but you have to do a cast in order to go the other way. (F)

7) The two operands of a binary operator must always be the same type. (F)

8) The result of an operator usually has the type of the wider operand. (T)

9) Aliasing occurs when you assign one double to be equal to another. (F)

10) A string in Java is a primitive type that holds a sequence of characters. (F)

11) Putting one string on the end of another is called concatenation. (T)

23) After assignment, variables on the right and left side have equal values. (F)
