ORGANIZE!!

Topics from your past…Ch 1• Fractions operations (+ - X / )• Rounding decimals – place names• Decimal to percent to fraction• Order of Operations: PEMDAS (MD, AS left to right as a grouping) • Factoring:• Prime & Composite numbers• Primes: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47 • Prime Factorization (make tree) • Least Common Multiple (LCM)• Ex: find the LCM of 2, 5, 6, 9 • LCM=90

The Real Number Line and Inequalities

1.1a

Real Number Classifications• Real Numbers: the numbers found on a Number Line Hawkes slide 11

• Irrational Numbers: decimals repeating without a pattern (pi, e, non-perfect square roots)

• Rational Numbers: zero, non-decimals, fractions, repeating decimals, perfect squares

• Integers: positive/negative non-decimal numbers, zero

• Whole Numbers – zero, positive integers

• Natural (counting) Numbers – positive integers

• Example: Classify 7 in the Real Number System• Try it… Classify -1/2 in the Real Number System

Number Line

• Draw a number line• Label the number line• Plotting points

Inequalities

• Inequality Symbols – Hawkes slide 17• Read either left to right or right to left• Example: show on a number line all • Comparing fractions: rewrite with a common

denominator if you can’t determine• Example: Graph and compare ¾ and 2/3
