In this post we will try to learn subtraction of two digit numbers. Before going through this chapter, make sure you have clear understanding of of basic subtraction which we have discussed in our previous post.
Subtraction of Two Digits
In order to subtract the two digit number, first we have to vertically align the number such that the digit in “ones and tens place” of both the number are aligned in the same line.
After aligning all the digits in proper order we have to subtract the individual digits to get the right answer.
The Large number from which small number is subtracted is called Minuend
The smaller number which is subtracted is called Subtrahend
The number we get after subtraction is called Difference
Let us understand the concept with the help of example.
Example 01
Subtract 36 – 14 = ?
Solution
Here 36 is Minuend
14 is Subtrahend
Do the following steps to calculate difference
Step 1: Align both the numbers vertically such that digit in ones and tens place are in the same line
Step 2: Now we have to start subtraction from right corner
First subtract the digit in ones place (6 – 4 = 2 )
Step 3: Now subtract the digit present in Tens place (3 – 1 = 2 )
Hence the value of subtraction 36 – 14 = 22
Example 02
Subtract 75 – 31 = ?
Solution
Here 75 is Minuend
31 is Subtrahend
Step 1: Align both the numbers vertically such that digit in ones and tens place are vertically in the same line
Step 2: Now we have to start subtraction from right corner
First subtract the digit in ones place (5 – 1 = 4 )
Step 3: Now subtract the digit present in Tens place (7 – 3 = 4 )
Hence the value of subtraction 75 – 31 = 22
Example 03
Subtract 25 – 13 = ?
Solution
Here 25 is Minuend
13 is Subtrahend
Step 1: First align the numbers vertically such that digits in tens and ones place are in line
Step 2: First subtract digits present in Ones Place ( 5 – 3 = 2)
Step 3 : Now subtract digits in Tens Place ( 2 – 1 = 1 )
Hence the value of subtraction is:
⟹ 25 – 13 = 12
Example 4
Subtract 98 – 97 = ?
Solution
Here 98 is Minuend
97 is Subtrahend
Step 1: First align digits in tens and one place in vertical manner
Step 2: Now start subtraction from the right end (digits in Ones place)
Step 3: Now subtract digits in Tens Place ( 9 – 9 = 0 )
Hence the value of subtraction is:
⟹ 98 – 97 = 01
Example 5
Subtract 60 – 60 = ?
Solution
Here 60 is Minuend
60 is Subtrahend
Step 1: First align numbers vertically such that digits in Tens and Ones place are in the same line
Step 2: First subtract digits in ones place ( 0 – 0 = 0)
Step 3: Now subtract digits in Tens place ( 6 – 6 = 0)
Hence the value of subtraction is:
⟹ 60 – 60 = 00
Now you have understood the concept of subtraction of two digit number, it is now time to practice some related questions. In the below section we have provided you with subtraction questions, all you have to do is to solve the problems and select the right option.
