  1. For each of the following examples, write down the arithmetic operator symbol missing from the statement. For example: 1 _ 2 = 3 is missing the + operator.
  1. 4 _ 2 = 8
  2. 3 _ 5 = 8
  3. 2 _ 3 = 8
  4. 10 _ 3 = 3
  5. 13 _ 3 = 10
  6. 9 _ 3 = 3
  7. 2 _ 6 = 12
  8. 9 _ 1 = 9
  9. 9 _ 0 = 0
  10. 3 _ 0 = 1
  1. Using your knowledge of operator precedence, write down the result of the following expressions:
  1. 15 / 5 + 9 / 3
  2. ( 5 + 5 ) / ( 5 + 5 )
  3. ( 5 + 5 ) / 5 + 5
  4. ( 2 + 2 ) ^ 2 + 2 ^ 2
  5. 9 % 4 + 7
  1. Add one set of parentheses (opening and closing) to the following expressions, so that the revised expression equates correctly to the value stated:
  1. 1 + 2 * 3 + 4 = 15
  2. 5 * 6 - 4 ^ 0 = 1
  3. 1 * ( 5 + 6 ) * 2 = 17
