Adding and subtracting polynomials

The  exercise appears under the Algebra I Math Mission. This exercise adds and subtracts polynomials of various degrees

Types of Problems
There is one type of problem in this exercise:


 * 1) Add or subtract the polynomials: This problem has an arithmetic problem asking the student to add or subtract two polynomials. After finding the answer, the answer is to be typed in to an answer box on the right.Aasp1.png

Strategies
Knowledge of addition and subtraction, specifically collecting like terms, is all that is needed to complete this exercise.
 * 1) Typing in the answer using ^ is slow, making the efficiency badges challenging with current timing levels.
 * 2) This exercise is mislabeled, as there is no multiplication or factoring occurring in the problem.

Real-life Applications

 * 1) Polynomials can be used via power series to represent many complicated functions and calculus is simpler to perform on polynomials than other functions. Thus any comfort with polynomials should increase calculus ability.
 * 2) Factoring polynomials is an important skill in solving inequalities and equations with polynomials.
 * 3) Factoring polynomials can be used for solving equations with polynomials, such as those that appear in many business models.
