Adding, Subtracting, Multiplying, and Dividing Integers Study Cards (7th Grade)

Question	Answer
Integer	a number that has a direction (shown by the sign) and a distance (shown by the absolute value)
Direction of an Integer:	Positive - right of zero Negative - left of zero
Absolute Value	the distance from zero. Absolute value has no sign. It is NOT positive or negative.

Disk/Chip Model	is based on using two different chips to represent positive and negative values (basically, another way to show work for adding or subtracting negative or positive integers)
