Think And Subtract

Subtraction can only be performed by subtracting smaller number from bigger number.

Steps to perform the subtraction:

  • Analyse the two numbers
  • First take the bigger number.
  • Write it above the smaller number..
  • Then subtract the smaller number from bigger number.
  • For example let us subtract the smaller number from the bigger number for the following pair of numbers

    191, 465

    The two numbers are 191 and 465. On analysing the pair we find that 465 is bigger and 191 is smaller

    We will first take the  bigger number 465

    We will write 465 above 191 as 43 is the smaller number

    We will then perform the required subtraction

    465 - 191 = ?

    Non we will perform the subtraction

    The answer is 274.

    Illustration 1: For the pair of numbers 782 and 308 which of the following option represents the correct relation

    A. 782 - 308 = ?

    B.  308 - 782 = ?

    C. Both A and B are correct

     Both A and B are incorrect
