What does PEMDAS or GEMS stand for?
PEMDAS- Parentheses, Exponents, Multiplication and Division, Addition and Subtraction
GEMS- Grouping, Exponents, Multiplication/Division, and Subtraction/Addition
What is the Rule of Exponents when it comes to the product of powers? In other words when we multiple with the same base
Provide an Example
When we multiple exponents with the same base, we keep the base and add our exponents.
am x an = am+n
23 x 24 = 23+4= 27
Solve this Polynomial
(3x + 2) + (5x + 3)
Solve this Polynomial

Adding Integers
-6 + -12 = -18
-5 + 14 = 9
23 + -8 = 15
34 + -74 = -40

What is the Rule of Exponents when it comes to the Quotient of Powers? In other words when we divide with the same base
Provide an Example
Division Rule
When dividing by same bases with exponents, we keep the base the same but subtract our exponents
ax/ay= ax-y
26 / 24= 26-4 = 22
Solve this Polynomial
4x - 3 - 2x + 6
Solve this Polynomial
4x - 3 - 2x + 6
4x - 2x -3 +6
2x + 3
Subtracting Integers
-35 - -49
-20 - 18
-15 - -15
48 - -52
Subtracting Integers
-35 - -49 = -35 + 49 = 14
-20 - 18 = -38
-15 - -15 = -15 + 15 = 0
48 - -52 = 48 + 52 = 100
What does "like terms mean"?
Provide an example to your explanation
Explanation and example will vary
Solve the following problems using PEMDAS or GEMS
(10-7) + (2 X 14 / 4)
(10-7) + (2 X 14 / 4)
3 + (28/4)
3 + 7

What is the Rule of Exponents when it comes to the Power of a Power? When an exponent is raised to a power
Provide an Example
Power to a Power Rule
When an exponent is raised to a power we multiply the two exponents and keep the same base
(ax)y= ax*y
(32)4= 32x4 = 38
Solve the following Polynomial
(2x - 3y + 5) - (-8 + y - 4x)
(2x - 3y + 5) - (-8 + y - 4x)
- (-8 + y - 4x) = +8 - y + 4x
2x - 3y + 5 + 8 - y + 4x
2x + 4x -3y -y +5 +8
6x -4y + 13
Multiply the following
-8 x -20
-5 x 13
9 x 14
12 x -2
86 x 0
-8 x -20 = 160 * multiplying two negatives gives us a positive answer
-5 x 13 = -65
9 x 14 = 126
12 x -2 = -24
-86 x 0 = 0 * zero times anything will always be zero

What is the Rule of Exponent when we have a Zero Exponent
Provide an example
Zero Exponent
Anything raised to the power of zero is 1
a0=1
1430=1
Solve the following Polynomial
3x (2x2 + 5x - 4)
3x (2x2 + 5x - 4)
3x (2x2) + 3x (+5x) + 3x (- 4)
6x3 + 15x2 - 12x
Dividing Integers
144 / - 12
-180 / 3
-81 / -9

144 / - 12 = -12
-180 / 3 = -60
-81 / -9 = 9

What is the Rule of Exponents when it comes to Negative Exponent
Provide an Example
Negative Exponent Rule
When we have a negative exponent, it becomes a fraction with the positive base and exponent in the denominator
a-x = 1/ax
7-6= 1/76
2 (5x - 4) - 3 (2x + 6)
2 (5x) + 2(-4) -3 (2x) - 3 (+6)
10x - 8 - 6x - 18
10x - 6x -8 - 18
4x - 26
