# Arithmetic/Part I Review and Test

## Notes[edit]

Remember that:

Any time a number __smaller__ than (LESS than) 0 is __added__ to a number __larger__ than (GREATER than) 0 you would use subtraction as shown below:

5+(-3)=5-3, therefore5+(-3)=2

Any number subtracted from itself always equals 0.

Any number above 9 will always have more than one digit.

The number line is very important in calculating numbers smaller than 0.
