Question

Show In The Number Line
a) -5+(-3)​

Answer 1

Answer:

Step-by-step explanation:

Explanation:

Numbers on a number line can be thought of as steps and the signs for each of these number as the respective direction of those steps.

For example,

If I define my positive sign as moving from left to right then negative sign represents movement from right to left.

Now the number  

3

means  

3

steps in the positive direction and similarly  

−

3

means  

3

steps in the negative direction.

Now on the number line the starting position is usually called the origin which is  

0

.

Hence,  

3

+

(

−

3

)

means walking  

3

steps in the positive direction (i.e. from  

0

taking  

3

steps we end up at point  

3

on the number line) and  

−

3

means walking  

3

steps in the negative direction from the previous position (i.e. from  

3

taking  

3

steps back in the opposite direction we end up at  

0

on the number line.)
