Evaluating expressions with parentheses

The  exercise appears under the 5th grade (U.S.) Math Mission, 6th grade (U.S.) Math Mission and Pre-algebra Math Mission. This exercise practices proficiency and confidence with translation into math-talk and order of operations.

Types of Problems
There are two types of problems in this exercise:


 * 1) Find the value of the expression: This problem has an arithmetic expression that makes use of parentheses. The student is expected to find the correct result and write it in the space provided.Eewp1.png
 * 2) Select the correct translation: This problem has an English sentence and several possible mathematical translations. The student is asked to select the translation that correct represents the meaning of the sentence from a multiple choice listing.Eewp2.png

Strategies
Knowledge of the order of operations and confidence with mathematics vocabulary are encouraged to ensure success on this exercise.
 * 1) The order of operations is PEMDAS which means things in parentheses should be completed first, before continuing on to Exponents, Multiply/Divide, and finally Add/Subtract.
 * 2) Research indicates the answer choice for Select the correct translation will have parentheses, so if none are there it is not the answer.

Real-life Applications

 * 1) An ability to translate from English into math and vice versa is important in all parts of mathematics.
