The difference of 5 and - 8 increased by the sum of - 4 - 11 is?

-2

Step-by-step explanation:

You have to write it just as the question states it.

5 - (-8) = 5 + 8 = 13

-4 + - 11 = - 4 - 11 = - 15

It is hardly an increase. In this case increase means addition. The math sentence would be written as

13 + - 15 = 13 - 15 = - 2
