Yes. Both the commutative property of addition, and the commutative property of multiplication, works:* For integers * For rational numbers (i.e., fractions) * For any real numbers * For complex numbers
The question has no sensible answer because its proposition is not true. Multiplication is commutative, division is not, so the rules are NOT the same.
Numbers, by themselves are neither commutative nor are they non-commutative. Commutativity is a property that belongs to a mathematical operation on a set of numbers. However, since the question does not specify what operation you have in mind, it is not possible to give a more helpful answer. The basic operations of arithmetic are addition, subtraction, multiplication and division, but there are many more mathematical operations.
Subtraction is not commutative nor associative.
No, it is not. Division by zero (a rational) is not defined.
