Closure Property(Integers)

1. Addition : Adding two integers gives an Integer, so Integer satisfy closure property.For example

  2+3=5

2 and 3 are integers,so 2+3=5 , will be also an integer.

2.Subtraction : Subtracting an integer from another one yields an integer.So, Integer satisfy closure property with respect to Subtraction.

For example

  2-3=-1

2 and 3 are integers,so 2-3= -1 , will be also an integer.

3.Multiplication: Multiplication of an Intreger with another integer result in an integer.So, Integer satisfy closure property with respect to Multiplication.

 For example

  2×3=6

2 and 3 are integers,so 2×3=6 , will be also an integer.

4.

Integers are not closed under divison.Because

   \rightarrow \frac{a}{b}\neq \frac{b}{a}\\\\\frac{2}{3}\neq \frac{3}{2}
