1. Commutative Property of Addition/Multiplication – The word, commutative, from French, commuter (to switch), means move around. Such as in problem, a {\displaystyle a} • b {\displaystyle b} = b {\displaystyle b} • a {\displaystyle a} , the a {\displaystyle a} and the b {\displaystyle b} move around about the equal sign, but nonetheless, still equal to the same sum (in this situation, we can say gas house edwards co c {\displaystyle c} ). Now, let’s implement this on real numbers, such as:

2. Associative Property of Multiplication/Addition – Etymology here: The word, associative, is derived from the word associate, which electricity facts for 4th graders comes from the Latin word, associo, which means to unite together, associate. This property basically reflects the same rules as the Commutative property: No matter the order of the parentheses, you will get the same result. The parenthesis can go wherever you like it to be! So:

3. Identity Property – Specifically the Additive Identity Property and the Multiplicative a gas station near me Identity Property, is when the total (number) does not change throughout the equation. The word, identity, comes from the Latin word for idem, which means the same. So, you can think of it as the number is still the same after the math equation. In 5 {\displaystyle 5} + 0 {\displaystyle 0} = 5 {\displaystyle 5} : The total (number) stayed the same throughout the math e payment electricity bill up problem–It is still 5! For the Additive Identity Property, it is always zero (this works for subtraction as well)–For the Multiplicative Identity Property, it is always one (this works for division c gastronomie vitam as well).

4. Inverse Property, also the Additive Inverse Property and the Multiplicative Inverse Property, state that any number to added to its opposite counterpart ( 5 {\displaystyle 5} and − 5 {\displaystyle -5} ) will equal either zero or one. This zero or one depends on which Inverse Property you are using gas and water company. If you are using the Additive Inverse Property, you should be getting zero. If you are using the Multiplicative Inverse Property, you should be getting one. The Additive Inverse Property works with subtraction as well, and the Multiplicative Inverse Property works with division as well. In the Additive Inverse Property, the was electricity invented during the industrial revolution number must to be added to its negative counterpart, such as 29 {\displaystyle 29} and − 29 {\displaystyle -29} , 6 {\displaystyle 6} and − 6 {\displaystyle -6} , 91 {\displaystyle 91} and − 91 {\displaystyle -91} , 47 {\displaystyle 47} and − 47 {\displaystyle -47} , etc.. In the Multiplicative Inverse Property, the number must be multiplied to its reciprocal, which electricity dance moms choreography is the number found by flipping the numerator and the denomerator of a fraction ( 2 {\displaystyle 2} = 2 1 {\displaystyle {\tfrac {2}{1}}} ), such as 3 4 {\displaystyle {\tfrac {3}{4}}} and 4 3 {\displaystyle {\tfrac {4}{3}}} , 9 2 {\displaystyle {\tfrac {9}{2}}} and 2 9 {\displaystyle {\tfrac {2}{9}}} , 82 93 {\displaystyle {\tfrac {82}{93}}} and 93 82 {\displaystyle {\tfrac {93}{82}}} , 2 {\displaystyle 2} and 1 2 {\displaystyle {\tfrac {1}{2}}} , etc..

5. Property of Zero – Specifically the Multiplicative Property of Zero and the Additive Property of Zero, is when zero plays a role in a math equation. Specifically in the Multiplicative Property of Zero, anything multiplying zero gas works park fireworks is zero. This rule is true no matter what number it is. Big or small, this rule works in every and all cases of problems that follow the Multiplicative Property of Zero. For example:

The Additive Property of Zero is part of the property of zero group and the identity group, which will be explained later in this section. The Additive Property of Zero states that british gas jokes any number adding zero will remain the same (thus, identity): r {\displaystyle r} + 0 {\displaystyle electricity electricity lyrics 0} = r {\displaystyle r} . Here are a few problems to help explain:

6. Substitution property is the act of substituting factors with the answer. An example is − 5 x + 8 + x = − 4 x + 8 {\displaystyle -5x+8+x=-4x+8} . The substitution property simple takes − 5 x {\displaystyle -5x} , and adds it to x {\displaystyle x} , which equals − 4 x {\displaystyle -4x} and the constant: 8 {\displaystyle 8} (since there are no like terms).
