Question

Height of a place A is 1800 m above sea level
Another place B is 700m below sea level
I what is the difference between the levels
of these two places ?​

Answer 1

Height of place A = 1800 m from the sea level

Height of place B = -700 m from the sea level (i.e 700 below the sea level)

so the difference in the height is 1800 -(-700)

1800 + 700 = 2500m

✅ Hope you will understand it .
