INTRODUCTORY EXERCISES

(3)

Draw the portion of the number line between -2 500 and -2 000. Mark -2 330 on this line.

SOLUTION:

It would be impractical to mark all the integers between -2 500 and -2 000 on the line, so we can just mark in the multiples of 100 as follows:

_________________________________________________________
-2500      -2400       -2300      -2200       -2100       -2000

To plot the number -2330 on the line, we note that -2330 is almost half way between -2300 and -2350, so we get:

________________________________________________________
-2500      -2400       -2300     -2200      -2100      -2000
                     -2330
