Who’s or Whose ? Use of Apostrophe – The Editor’s Manual
An apostrophe does indicate possession but only with nouns (e.g., the cat’s whiskers, my parents’ home), which is why apostrophe use can get confusing.Just remember that an apostrophe is never needed to form the possessive of a pronoun.

Definition: Subtraction. Subtraction is the process of determining the remainder when part of the total is removed. Suppose the sum of two whole numbers is 11, and from 11 we remove 4. Using the number line to help our visualization, we see that if we are located at 11 and move 4 units to the left, and thus remove 4 units, we will be located at 7.
