On the following number line, (-4) × 3 is represented by the point
Solution:
The requirement of the above question is to represent the simplified value of expression (-4) × 3 on the number line.
The given expression is (-4) × 3 = -12
As per number line rules and integer rules we know that all the negative integers lie at the left hand side of zero and the positive integers lie at the right hand side of the zero.
In the given number line we can see that each division is of 2 units. So, starting from the left of 2 let us mark the integers as:
J = 0
I = -2
H = -4
G = -6
F = -8
E = -10
D = -12
C = - 14
B = - 16
A = -18
According to the marked integers Point D on the number line represents (-4) × 3 = -12
✦ Try This: On the following number line, (-8) × 2 is represented by the point.
We can apply integer rules and the number line rules to represent the value of (-8) × 2 = ____.
