Addition along with subtraction, multiplication and division are the four basic operations of arithmetic. Addition operation is represented by the sign ‘$+$’ (read as ‘plus’). The addition of two numbers gives the total amount of those values combined. Subtraction is also a basic operation of arithmetic and is represented by the sign ‘$-$’ (read as ‘minus’). The subtraction is the operation of removing objects from a collection. The result of subtraction is called difference.
Now, it is given that the Meena’s present age is ‘$k$’ years and we have to find her age 2 years after and 7 years ago. We need to add 2 to her present age to get her age after 2 years and we need to subtract 7 from her present age to get her age 7 years ago.
Hence, her age after 2 years is ‘$k+2$’ years and her age before 7 years is ‘$k-7$’ years.
