1
Goal: Graph, order and use real numbers
2
Order numbers from least to greatest: 1. 0.95, 0.09, 0.192, 0.79 2. 3.55, 3.3, 0.3, 3.13 3. ½, 3/5, ¼, 5/16
4
Real number line: real numbers are pictured as points. The numbers increase from left to right. Origin: the point labeled 0 on a real number line. Graph (of a number): the point on a number line that corresponds to a real number Coordinate (of a point): the number that corresponds to a point on a number line
6
A number line can be used to order real numbers. The inequality symbols, > can be used to compare two numbers
7
Graph the numbers -1 and -4. The compare them using the symbol.
10
Opposite (additive inverse): of any number a is –a Reciprocal (multiplicative inverse): of any nonzero number a is 1/a
12
Show how you can use the distributive property to evaluate 5 ● 203.
13
Subtraction is defined as adding the opposite. Division is defined as multiplying by the reciprocal.
14
A. Find the difference of 4 and -9. B. Find the quotient of - 15 and 1/3.
15
A. What is the quotient of -16 and ½ ? B. What is the product of -5 and 8?
17
p. 6-8 15-26, 30-38, 42-49, 51-54, 63-77 odd
