We need to find the correct answer on the given choices:


If a >
0 and b < 0, then The answer is a + b > 0

let’s give a specific example:

let’s have a = 1

and b = .20

Now,
let’s try calculating if our answer is correct.

Thus a + b > 0

=> a + b

=> 1 + .20

=> 1.20

and 1.20 is greater than 0.

=>Therefore 1.20 > 0 = a + b > 0
