Answer:
Mathematics often involves simplifying numerical expressions. When doing so, you can use laws and properties that apply to particular operations. The multiplication property of 1 states that any number multiplied by 1 equals the same number, and the addition property of zero states that any number added to zero is the same number.
Two important laws are the commutative laws, which state that the order in which you add two numbers or multiply two numbers does not affect the answer. You can remember this because if you commute to work you go the same distance driving to work and driving home as you do driving home and driving to work. `You can move numbers around in addition and multiplication expressions because the order in these expressions does not matter.
You will also learn how to simplify addition and multiplication expressions using the associative laws. As with the commutative laws, there are associative laws for addition and multiplication. Just like people may associate with people in different groups, a number may associate with other numbers in one group or another. The associative laws allow you to place numbers in different groups using parentheses.
