Answer 2

Answer:

The number of trees remained in the society is 69.

Step-by-step explanation:

Given in a particular area, during a month 15 trees were cut.

In the same area,  84 trees were planted.

Represent cutting off the trees by negative numbers, therefore, the number of trees that were cut $= -15$.

Represent the planted trees by positive numbers, therefore, the number of trees that were planted $= +84$.

Following the rules of addition of integers, the addition of negative number with the positive number is nothing but the subtraction.

Since the positive number is larger, the result is also a positive number.

Thus, the final result is

$(-15)+84=69$

Therefore, the number of trees remained after and planting in the society is 69.
