Suppose my weight 1 year ago was 95 kg

My weight now is 100 kg

So, I have increased 5 kg

 

But

If my weight becomes 85 kg

Then, I have reduced 10 kg

 

But these 5 kg & 10 kg aren’t the same

One is positive, + 5 kg

Other is negative , −10 kg

 

Similarly

  If we deposit 200 rupees to the bank

  It is positive, +200

  If we withdraw 500 rupees from the bank,

  It is negative −500

 

Similarly

Plane is 5000 m above sea level .

  It is positive, + 5000 m

Submarine is 1200 m below sea level .

  It is negative , −1 2 00 m.

 

Therefore ,

  Just like positive numbers : 1, 2, 3, 4, 5, …...

  We have negative numbers : −1, −2, −3, −4, −5, …….

 

What about 0?

0 is neither positive, nor negative.
