Part I review-

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:

    example: 5+(-3)=5-3, therefore 5+(-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.
