QUESTION REVIEW In this article, I will set some  Fraction Question.  Let see what you got. QUESTION 1.  $ 81 \div 3 \div 2 \div 3 $      2.  $ 81 \div 3 \div \frac{2}{3} $ 3.  $ 81 \div \frac{3}{2} \div 3 $       4.  $ \frac{81}{3} \div 2 \div 3 $ 5.  $ \frac{81}{3} \div \frac{2}{3} $       6.  $ \frac{81}{3} \over \frac{2}{3} $ 7.  $ 1\frac{1}{2}3 $       7.  $ 1\frac{1}{2}3 + 2\frac{3}{4}2 - 1\frac{1}{4} $

TOPIC OVERVIEW In this article, I will explain the use of the Commutative Law of Addition , and suggest a better way of thinking about the topic. Please add your ideas in the comments. THE COMMUTATIVE LAW ("change" the order of the numbers or letters) Over the years, people have found that when we add or multiply, the order of the numbers will  not affect the outcome. " Switching " or " changing " the order of numbers is called " commuting ". When we change the order of the numbers, we have applied the " Commutative Law ". In an addition problem, it is referred to as the " Commutative Law of Addition " such that Addition on the Real Number ( 2, -5, and $ \frac{2}{7} $  )  S , T it is true  that    S + T = T + S THE SUM OF 2 REAL NUMBERS Example Real Numbers 2 & 3 Let make S=2 & T=3 Solution S+T = T + S 2+3 = 3 + 2 5 = 5 Note: - This is the sum of 2 positive real numbers.  S

TOPIC OVERVIEW In this article, I will explain the use of a Like Term, and suggest a better way of thinking about the topic. Please add your ideas in the comments. Like Term : This is a term whose variables are the same. in other words, terms that are "Like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different. Example 7 x x -2 x Are all  like terms  because the variables are all x (1/3) xy 2 −2 xy 2 6 xy 2 xy 2 /2 Are all  like terms  because the variables are all x Unlike Term :  If they are not like terms, they are called " Unlike Terms ": Unlike Terms Why they are "Unlike Terms" −2 xy −4 y 13 y 2 ←  these are all  unlike terms   (  xy ,  y  and  y 2  are all different) 2 x       2 x 2      2 y       2 xy These are all  Unlike Terms  because the variables and/or their exponents are different.
