Practice set 5, asks that we draw a number arrow for each of the following.
And problem number one says a positive 2
starting at -4. Positive numbers can
be pictured as arrows,
which point to the right and negative
numbers can be pictured by arrows
which point to the left. So it's asking
us to start at -4
I need to find that location on a number
line. With the scale already
indicated here I have a -1 to the left is -2, -3
here's the -4 starting place
and then it's asking us to indicate
a positive 2, positive numbers are
in the direction to the right
and the length of the arrow indicates
the number that we're adding. This would
be the
+2. Problem number two
asks us to indicate a number line
with a -5 starting at the 3,
again a scale is here,
1, 2, 3 as my starting place and their
asking as to indicate
an arrow with a -5. Negative is to the
left
and the -5 is
an arrow having a length of
5 spaces.
1, 2, 3, 4, 5
