Negative numbers represent values below zero
and positive numbers represent values above zero
an example would be above and below ground or sea level( a bird is flying 5 meters above the lake and a fish is flying 6 meters directly under the bird how much is the difference between them)
How do you figure out if a integer statement is a addition statement or subtraction?
you check the operation
eg 1+(-2)=(-1) would be a addition statement
3-(-1)=4 is a subtraction statement
Opposite integers have the same numeral but different signs they always equal 0 like
(+5) -(-5)=0 also (+3)-(-3)=0
you can also solve them on number lines
Here is a game where you can play and learn about Integers
