  2. Numerical Expression: A mathematical phrase that includes numerals and operational symbols. It does not have an equal sign. Brackets: [[[[A pair of symbols used to group things together.]]]] Braces: The outer most grouping symbol used in mathematics. Parentheses: The symbols “(“ and “)” that are generally used for grouping. Operation: A mathematical process applied to solve a problem. Addition, subtraction, multiplication, and division are the four basic operations.

  3. 5 ( 3 ) • hint: numbers outside of parentheses should be multiplied by the inside value.

  4. 4 (7 – 2 ) • hint: complete operations inside of parentheses first.

  5. 11 ( 2 + 2 x 5 ) • hint: inside the parentheses, follow the order of operations; multiply before you add.

  6. 20 ÷ 5 – 1 x 3 • hint: when you have multiplication and division, work left to right.

  7. 10 ( 2 + 4 ) ( 14 ÷ 7 ) • hint: remember to complete parentheses first and move left to right.
