Exponents & Real Numbers
When you multiply two numbers with the same base, you ___ the exponents. EX: 52 x 53
add
How do you solve equations?
Inverse operations - opposite operation (add/subtract/multiply/divide)
What is the first step when graphing in slope-intercept form? y=mx+b
Graph the y intercept (b). Then you can use slope to find the other points.

Evaluate the expression;
42+6
42+6=
16+6=22
Evaluate the expression.
33 + 22 =
27 + 4 = 31
Solve
x + 15 = 32
x = 17
What is the y-intercept of the equation:
y=1/3x + 4
The y-intercept is 4
Find the Mean:
Data: 3, 5, 7, 7, 9, 11
Mean: 42 ÷ 6 = 7
Evaluate the expression:
7+2(4+1)
7+2(4+1)=
7+2(5) = 7+10
=17
Evaluate the expression:
52 _ 42 =
25-16=9
Solve
m - 28 = 36
m = 64
What is the slope of the equation:y=x-6
The slope is 1
Find the median:
Data: 12, 15, 18, 18, 21, 24, 27
Evaluate the expression;
23+4×6
23+4×6=
8 + 24 = 32
Evaluate the Expression:
(23 )(32)
(23 )(32) = 8 x 9=72
What is the first step when solving this equation?
2x = 100
Divide both sides by 2
What is the y-intercept of the equation:
y=-4x
The y intercept is 0 (at the origin)
Find the mean:
Data: 12, 15, 18, 18, 21, 24, 27
The mean is 19.3
Evaluate:
30÷(2+3)+7
30÷(2+3)+7 =
30÷ 5 +7 = 6+7=13
