COMPARING INTEGERS
Integers expand the number system to include negative numbers. The integers are the whole numbers and their opposites and also zero. First, we’ll investigate the number line and compare integers.
ABSOLUTE VALUE
Absolute value is a method used to express the positive value of a number. The absolute value of a number is the number’s distance from zero expressed as a positive number.
INTEGER OPERATIONS: ADDING AND SUBTRACTING INTEGERS
To compute with integers we must pay attention to the sign of the integer. We can use the number line to add integers, but to streamline the computation we will develop the rules for adding integers.
The definition for subtracting integers is to “add the opposite”. We can use the number line to subtract integers, but we can speed up the computation for subtraction by learning to write the subtraction problem as an addition problem where we change the second integer to its opposite. From there, we proceed by using the addition rules for integers.
