unlike signs.
Material required: Ruler, chart paper, pencil and
eraser.
S (2)

Step 1.
Step 2
Fig. 1.8
Draw two number lines parallel to each other
on a chart paper and mark integers.
Draw 2 times tables on the number lines
drawn as shown in Fig. 1.8.
Join 0 to 0, 1 to 2, 2 to 4, 3 to 6 to show
2 x 0 = 0, 2 x 1 = 2, 2 x 2 = 4,
2 x 3 = 6 by arrows.
Step 3.
Step 4.
Produce these arrows upwards to meet at
point S.
Step 5.
Draw dotted line arrows from S passing
through the negative integers on the upper
line.
These dotted arrows meet the integers on
the lower line as shown in Fig. 1.8. We find​
