Step-by-step explanation:

Given:

expression= (-2)+(-6)+(-9)

To find:

simplification

Solution:

The integers are solved without the brackets

So we take off the brackets from the numbers

(-2)+(-6)+(-9)

-2 - 6 -9 ...................... after opening the brackets the signs will be changed

Two negatives make a positive

So the last two integers 6 & 9 are added as both have negative signs

∴ -2 - 15

Similarly, the leftover terms are added as both are negative and we get

= -17

∴ (-2)+(-6)+(-9) = -17
