Real Numbers and Not Real Numbers

Posted by on October 30, 2014

This week in math class, we learned about real and not real numbers. A real number has two sections in it. It has rational and irrational numbers. Rational numbers are whole numbers, integers, decimals, whole square roots, and fractions. An irrational number is a square root that doesn’t go into itself or a decimal that does not terminate or repeat. A not real number is a square root with the negative sign in the square or a fraction with a zero as the denominator. It was pretty easy, but I learned a lot from it and I am glad we did it. I hope Mrs. Resnick keeps giving us easy things to learn.|
