The difference of gails age and 13 is 54

Answer 1

Question: "The difference of gails age and 13 is 54"

Whenever you think of the "difference" between numbers, think of how far you have to travel from one number to the other.

Gail's age is what we are trying to figure out. The space between this unknown number and the number 13 is 54 years.

Hmmm... That means Gail is either 54 years younger than 13 or 54 years older than 13.

13 - 54 = Gail's age

OR

13 + 54 = Gail's age

Which one makes sense?

Since 13 - 54 = - 41 then we know this is incorrect. Gail's age cannot be a negative number.

So! 13 + 54 = 67 = Gail's age.

Gail is 67 years old, because the difference between 67 and 13 is 54.
