Integers Whole Numbers Rational Numbers Use this space to take notes as you listen in class. Classifying Rational Numbers.

Unit 2 Integers and Rational Numbers Name: _____ Period: _____ Common Core State Standards CCNS.1 - Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram. REAL NUMBERS Since q is a non-periodic decimal, it is an irrational number, and the corresponding point is an irrational point. This suggests another way of interpreting real numbers. The real numbers are the collection of all decimal expansions, finite or infinite, such as , , .Absolute Value- The distance a number is from zero on the number line. An absolute value is never negative. Examples: l -5 l = 5 and l 5 l = 5. ADDING. Check for closure property under all the four operations for natural numbers. (ii) Integers We say that rational numbers are closed under addition. That is, for. Any number that contains a decimal point or Rational Numbers. Can be expressed as a fraction. Include integers and fractions or decimals. 1/2, 2/3. These are defined for any integers a and b, but, for the reasons .. We identify any integer b with the rational number j(b) =, writing b. All integers and fractions are rational numbers. • If the numerator and denominator of a rational number are multiplied or divided by a non-zero integer, we get a.
