These mean the same thing, but the first sounds like it is telling you where 3 is (3 is less than x), while the second sounds like a proper answer to the question "where is x?" (x is greater than 3). Weve flipped the wholeAssociated Topics: Middle School Algebra Middle School Negative Numbers. Students may discover that when drawing models for each product they need not trace algebra tiles as long as the units they use to represent 1Since 6 results in both sides having the same value, than the value of x must be greater than 6.Note: A transparency may be flipped for x or x . Symbol flipped when we multiply or divide by a negative! As the above problem illustrates, we can add, subtract, multiply, or divide on both sides of the inequality.The boundary line for x y 1 is x y 1, or y x 1. Since the equal sign is included with the greater than sign, the boundary line is solid. You have probably remembered in Algebra that if we multiply an inequality by a negative number, then the inequality sign should be flipped or reversed. For example, if we want to find the solution of the inequality , we multiply both sides by and reverse the greater than sign giving us . Just when you were getting used to dealing with numbers, along comes algebra! Suddenly all these xs and ys start sprouting up all over—as Mike Kelley so elo-quently >: If you flip the less than symbol around, you get the greater than symbol, which means the exact opposite of the < symbol. Plug in any value less than -5 and it does turn out to be more than 25, but why? Mathematically, why do we flip the sign here?The side that used to be more positive is now more negative. Also, imagine both sides of the inequality are positive. Then the greater side is the one with a higher Rules for Algebra www.juniorcertsolutions.com.
