List the order of operations method.
What is an approximation?
Rounding/estimate
When a bar is placed over a decimal, what does that make it?

What is the product of 2/5 and 2/4 in its simplest form? Identify if this is a terminating or repeating decimal.
1/5--terminating (.2)
Find the median:
4, 2, 6, 4.5, 3, 7.8, 2.6
Solve using the distributive property. Must show process for points.

5.4, 2.6, 3.7, 4.2, 8.9
5
Without doing calculations, is this number negative or positive.
-3^(2+3)
Negative, because to the 5th power (makes it negative).
What is difference between an improper fraction and an integer?
Improper faction turns into a mixed number and an integer is a whole number.
What is the quotient of 1/2 over 3/4 as an ellipses decimal?
.6... (repeating)

Define what mode is.
Mode: number that shows up the most in a list.
-19^0
Positive: anything to the 0th power equals one.
True or false: the reciprocal of an improper fraction keeps the fraction as an improper fraction.
False: when you flip the improper fraction, it turns into a proper fraction (since the numerator is smaller than the denominator).
