To find the distance between two points using their coordinates, when do you add their absolute values and when do you subtract them?
What is When the points are in the same quadrant, you subtract the absolute values of the coordinates that are different. When the points are in different quadrants, you add the absolute values of the coordinates that are different?
What are integers and how are they used to represent real-world quantities?
What is Integers are the counting numbers, their opposites and ) Integers are used to represent quantities in real-world situations such as..........(give example)
What does 1/2 equal as a decimal.
What is .50

When comparing two negative integers, how can you determine which integer is the greater number
What is the greater negative integer is the one closet to zero on the number line?
What does .25 equal as a fraction?
What does .75 equal as a fraction?
What is 1/4?
