The Evaluating expressions with parentheses exercise appears under the 5th grade (U.S.) Math Mission, 6th grade (U.S.) Math Mission, Pre-algebra Math Mission and Mathematics I 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:
- Find the value of the expression: This problem has an arithmetic expression that makes use of parentheses. The user is expected to find the correct result and write it in the space provided.
Find the value of the expression
- Select the correct translation: This problem has an English sentence and several possible mathematical translations. The user is asked to select the translation that correct represents the meaning of the sentence from a multiple choice listing.
Select the correct translation
Strategies[]
Knowledge of the order of operations and confidence with mathematics vocabulary are encouraged to ensure success on this exercise and for users to achieve accuracy badges and speed badges.
- 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.
- 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[]
- An ability to translate from English into math and vice versa is important in all parts of mathematics.
