Sure, let's find the sums step-by-step for each given pair of numbers:

(i) Find the sum of -18 and -7:

-18 + -7 results in combining two negative numbers.
When you add two negative numbers, you get a negative number.

So, -18 + -7 = -25.

(ii) Find the sum of 17 and -13:

17 + -13 involves combining a positive number and a negative number.
The operation can be viewed as subtracting 13 from 17 as they have different signs.

So, 17 + -13 = 4.

(iii) Find the sum of -25 and 22:

-25 + 22 again involves one negative and one positive number.
This is similar to subtracting 22 from 25, keeping the sign of the larger absolute value.

So, -25 + 22 = -3.

(iv) Find the sum of -11 and 14:

-11 + 14 involves a negative and a positive number.
This can be viewed as subtracting 11 from 14, which leads to a positive result because 14 is larger in absolute value.

So, -11 + 14 = 3.

(v) Find the sum of 12 and -27:

12 + -27 combines a positive number and a negative number.
This translates to subtracting 27 from 12, resulting in a negative outcome.

So, 12 + -27 = -15.

Therefore, the sums are:
(i) -25
(ii) 4
(iii) -3
(iv) 3
(v) -15
