How to Do Subtraction Step by Step with Examples
Subtraction is one of the four basic arithmetical operations being used in mathematics for solving problems. The process of subtraction always starts from the right side of a number and moves to the left like addition. Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers. This article will help kids in building their concepts about what subtraction is and how to subtract two numbers using the rules of subtraction. This uses images and examples to illustrate the topic deeply and differently. So, Let's begin with the understanding of our topic.
Define Single Digit Subtraction
A single-digit subtraction involves only a one-digit number i.e. 0 to 9 to subtract a number from the other one-digit number. Some basic terms used in subtraction include Minuend, which is the larger number from which the smaller number, known as the subtrahend, is to be subtracted. The result of their subtraction is known as the difference.

Rules of Subtraction
Various rules to be followed in performing subtraction are given below:
Check whether the given top number is smaller or larger than the bottom number.
If the given top number is greater than the bottom number, then subtraction starts from the right digit of the number and goes on till the last digit.
Subtraction of a Greater Number with a Smaller Number
If the given top number is smaller than the bottom number then subtraction takes place by borrowing one from the next digit on the left.
Subtraction of Greater Number with Smaller Number by Taking Carry
Further, repeat step 2 to subtract the entire quantities.
Subtraction Sign Rules
Rules for taking the signs in case of subtraction are given below:
When both numbers are negative, the result will always be positive.
When any one of the numbers is positive and the other is negative, the result will depend on the sign of the greater number.
When both numbers are positive, the result will always be positive.

Subtraction Examples
Some examples of subtraction for kids are discussed below:
Example 1: Subtract 1 from 6
Ans: As 6 is a greater number, so subtract 1 from 6, and we get 5 as the difference.
Example 2: Subtract 5 from 7
Ans: As 7 is a greater number, so subtract 5 from 7, and write the answer.
Showing Subtraction of Two Whole Numbers
Thus the difference between 7 and 5 is 2.
Single Digit Subtraction Worksheets
Single-digit subtraction worksheets are given below:
6 - 3 = (Ans: 3)
3 - 2 = (Ans: 1)
4 - 3 = (Ans: 1)
5 - 1 = (Ans: 4)

Ans: 8
Summary
Subtraction is one of the most basic and important operations used in maths. It creates a strong base for children in calculating the quantities accurately. It has wide applications in one's daily life. Subtraction is the base of learning several topics in mathematics, namely place values, word problems, mensuration, etc. It helps children in developing their mental ability and problem-solving skills. This article has covered all the details about what is subtraction, and the rules for subtraction and single-digit subtraction. If in doubt, ask in the comments.
FAQs on Subtraction for Kids Explained in Simple Ways
1. What is subtraction in math for kids?
Subtraction is the mathematical operation of taking one number away from another to find the difference. In simple terms, subtraction tells us how many are left.
- The number you start with is called the minuend.
- The number you take away is the subtrahend.
- The answer is called the difference.
2. How do you subtract numbers step by step?
To subtract numbers, line them up by place value and subtract from right to left. Follow these steps:
- Write the numbers one under the other.
- Start subtracting from the ones place.
- If the top digit is smaller, borrow from the next place value.
- Continue to the left.
3. What is borrowing in subtraction?
Borrowing in subtraction means taking 1 from the next higher place value to help subtract a smaller digit from a larger one. It is also called regrouping.
- If the top digit is smaller than the bottom digit, borrow 1 from the next column.
- Add 10 to the current digit.
4. What is the difference between subtraction and addition?
The main difference is that addition combines numbers while subtraction takes one number away from another. Addition increases the total, while subtraction decreases it.
- Addition example: 6 + 4 = 10
- Subtraction example: 10 − 4 = 6
5. Can you give an example of subtraction for kids?
A simple subtraction example is 9 − 5 = 4. This means if you have 9 items and take away 5, you have 4 left.
- Start with 9 apples.
- Take away 5 apples.
- Count the remaining apples: 4.
6. What are the parts of a subtraction problem?
The parts of a subtraction problem are the minuend, subtrahend, and difference. These terms describe each number in the subtraction sentence.
- Minuend: The number you start with.
- Subtrahend: The number you subtract.
- Difference: The answer.
7. How do you subtract with zeros?
To subtract with zeros, you may need to borrow from the nearest non-zero digit to the left. Zeros require careful regrouping.
- Move left until you find a non-zero digit.
- Reduce it by 1.
- Turn the zeros in between into 9s.
8. What is subtraction on a number line?
Subtraction on a number line means moving left from a number to find the difference. Each step left represents subtracting 1.
- Start at the larger number.
- Move left the number of steps you are subtracting.
9. Why is subtraction important in everyday life?
Subtraction is important because it helps us find out how many are left or how much more is needed. It is used in daily math situations.
- Calculating change when shopping.
- Finding the difference between two amounts.
- Checking remaining time or distance.
10. What are common mistakes kids make in subtraction?
Common subtraction mistakes include forgetting to borrow, misaligning place values, and subtracting in the wrong order. These errors can change the difference.
- Not lining up digits correctly.
- Forgetting to regroup when needed.
- Subtracting the larger digit from the smaller without borrowing.
