Learn About Integers
How to Add Integers
Same signs- Add the absolute values and use the common sign. ex. 3+5=8 -3+(-)5=-8
Different signs- Subtract the lesser absolute value from the greater absolute value. Then use the sign of the number with the greater absolute value. ex. -7+10=3 7+(-10)= -3
How to Subtract Integers
To subtract an integer add its opposite. ex. 7-(-)5= 12

Absolute Value- the absolute value of a number is its distance from zero on a number line, the absolute value of a is written |a|
How to Multiply Integers
The product of two negative integers is positive ex. -4(-6)=24
The product of a positive integer and a negative integer is negative ex. 2(-8)=-16
How to Divide Integers
Different Signs- the quotient of two integers with different signs is negative ex. 12÷ (-4)=-3
Zero- the quotient of zero and any nonzero integer is 0 ex. 0÷13=0
