Real Numbers

  1. 1. Real numbers <br />Nyricejones 839<br />
  2. 2. What are rational numbers <br />A. natural numbers <br />B. whole numbers <br />C. even and odd numbers <br />D. Integers <br />E. Repeating decimals <br />F. Terminating <br />G. Perfect squares and their roots <br />
  3. 3. Natural numbers <br />Another name for natural numbers is counting numbers <br />Natural numbers go from 1 to positive infinity <br />{1,2,3,4,5………}<br />
  4. 4. Whole numbers <br />“whole in your pocket” <br />Starts with a zero and goes to positive infinity <br />{1,2,3,4,5........}<br />
  5. 5. Even numbers <br />Even numbers end in 0,2,4,6, or 8 <br />Think of the “2x”table<br />Only look at the last digit of the numbers <br />
  6. 6. Odd numbers <br />Odd numbers end in 1,3,5,7 or 9<br />{1,3,5,7,9,11,13,15,17…}<br />Only look at the last digit of the number<br />
  7. 7. Integers<br />Integers are positive numbers and their opposites [negatives],plus zero <br />Positive [+] numbers are to the right of zero <br />Negative numbers are o the left of zero <br />Zero is neither positive nor negative. It is a neutral numbers <br />
  8. 8. Repeating decimals <br />Repeating decimals are decimals that keep on going but must have a pattern<br />Usually repeating decimals have a bar over the number or …at the end of the number<br />1/9,2/3,.3333….<br />
  9. 9. Terminating Decimals <br />Terminating decimals are decimals that come to an end and stop<br />½, ¾, 7, .9876, 3.0<br />
  10. 10. Perfect Squares and their roots<br />Perfect Squares have an exponent of two<br />They are called perfect squares because their answers actually create a square<br />(1.4.9.16.25.36.49.64.81.100.121.144.169.196.225)<br />Perfect square roots are square roots where one number times itself will give you the answer inside the “radicand”<br />
  11. 11. Irrational numbers<br />Irrational numbers are number that keep on going WITHOUT a pattern.<br />Any decimal that keeps on going in a calculator and has no pattern is irrational.<br />Any square root that is not perfect is irrational.<br />Pi is irrational because it is 22/;7 or 3.1415926535…<br />
  12. 12. Imperfcet square roots<br />No number multiplied by itself will ever give you the number located inside the “radicand”<br />If you do the square root of a number in a calculator and you get along decimal that has no pattern, it’s imperfect<br />
  13. 13. Real numbers <br />Real numbers are all number in this powerpoint presentation.<br />They are rational and irrational numbers.<br />
