D AY 142 U NDERSTANDING CLOSURE WITH POLYNOMIAL

I NTRODUCTION Operations on numbers or sets of the same category can be said to produce a member of the same category or not. This is a description of closure or non-existence of closure. Closure exists when the operation will lead to a member of the same category. In this lesson, we are going to discuss the closure of polynomials.

V OCABULARY :  Polynomials These are numbers whose power on the variables are positive whole numbers  Closure The a description of a situation where an operation on numbers of the same category gives rise to number of the same category as the first ones

 Closure Addition When polynomials are added, we get a result that is still get a polynomial. Thus, polynomials are closed under addition. Subtraction When polynomials are subtracted from each other, we get a result that is still get a polynomial Thus, polynomials are closed under subtraction.
