Closure & Commutative Prop. of Rational Numbers

The video tutorial explains rational numbers, which can be expressed as fractions or decimals. It covers the closure and commutative properties of whole numbers, integers, and rational numbers. The closure property is discussed in terms of addition, subtraction, multiplication, and division, highlighting that rational numbers are closed under addition, subtraction, and multiplication but not division. The commutative property is also examined, showing that addition and multiplication are commutative for rational numbers, while subtraction and division are not.
