The Properties of Multiplication
Properties are the rules of multiplication and make problem solving easier.
1. Commutative- It doesn't matter what order you multiply 2 numbers. The answer is always the same. Ex: 2x3=3x2
2. Associative-When multiplying 3 or more numbers together, it doesn't matter how you group them together. The answer will always be the same. Ex: (3x4)x7=3x(4x7)
3. Identity-When multiplying a number by 1 the answer is always the same number. Ex: 7x1=7
