Let's identify and use integers!

***

You can use a number line to display numbers called integers. Integers are whole numbers, and the set of integers include the counting numbers, their opposites, and zero.

 Plot the points +4, -2, +5, -1 on a number line, this is what it looks like:

If the number is an integer, write its opposite.  If it is not an integer, write "no."

1.)    +120                 _____________

2.)    -1,000        _____________

3.)    +17            _____________

4.)    $-7\frac{9}{10}$          _____________

5.)    -12             _____________

6.)    $-20\frac{2}{3}$          _____________

7.)    +98.6         _____________

8.)    -63.4          _____________

9.)    -275           _____________

10.)    $+\frac{4}{5}$            _____________

Solve.

11.)     What integer could you use to represent the phrase "a loss of $3?" 

12.)    On a number line, which integer is the least distance from zero?

A.   +7

B.   -8
