# The height of a place A is 1800 m above sea level. Another place B is 700 m below sea level. What is the difference between the levels of these two places?

Answer :

Given: - Height of A above sea level = 1800m

The height of B below sea level = 700m

To find: - Difference between the height of A and B

Let Above sea level height as + sign and below as –ve sign

Now to find the difference between levels add them with their sign

Hence (+ 1800) + (– 700)

= + 1100 metres
