How to Solve 1 Digit Multiplication with Step by Step Examples

The repeated addition of one number in relation to another is represented by the multiplication of two numbers. In mathematics, multiplying is equivalent to adding equal groups. As we multiply, the number of things in the group increases. The product, the two factors, and the product are all components of a multiplication problem.

What are 1 Digit Numbers?

We are aware that the digits 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 are used to create all numbers. One digit, two digits, and even several digits can be used to construct various numerals. There are 9 single-digit numbers. 1 (one) is the smallest and 9 (nine) is the largest one-digit number. When used as a number, all the digits are converted to numbers.

What is Multiplication?

Multiplication in mathematics is the same as adding equal groups. The number of things in the group grows as we multiply. A multiplication problem has three parts: the product, the two factors, and the product. These figures can be fractions, integers, whole numbers, natural numbers, etc. When a is multiplied by b, either a is added to itself 'b' times or the other way around. In mathematics, besides addition, subtraction, and division, multiplication is a mathematical operation symbolised by the symbol "✖ ".


Important Terminologies Used in Multiplication:

The "factors" are often the numbers that need to be multiplied. Example 2 is a factor of 4. The "multiplicand" is the number that has to be multiplied, and the "multiplier" is the number by which it is multiplied. Normally, the multiplier comes first and the multiplicand comes second; however, sometimes the multiplicand comes first and the multiplier comes second.

Properties of Multiplication :

The properties of multiplication are certain rules that are used while multiplying numbers.

  • Commutative property of multiplication: The product is unaffected by the order of the multiplier and multiplicand.

For instance, \[\]\[3 \times 4 = 12\]and \[4 \times 3 = 12\]Thus, the result remains unaffected.

  • Associative property of multiplication: It states that altering the way the elements are grouped has no effect on the result.

For instance, \[[3 \times 9] \times 2 = 3 \times [9 \times 2]\]

  • Identity property of multiplication: It states that whenever we multiply any number with 1 we will get the number itself.

For instance, \[8 \times 1 = 8\]


Multiplication Steps:

From right to left, multiply the multiplicand by each of the multiplier's digits. Below the line, the product's units are written.

Each product's tenth position is added to the product after it.

For Instance: , if we take \[561 \times 3\] :

The first calculation is \[3 \times 1 = 3\]. The 3 is entered beneath the line.

Now, multiply 3 by 6 to get 18. The 1 from the tens place is saved and added to the subsequent multiplication once the eight is written below the line.

To finish, multiply \[3 \times 5\]to get 15. The 1 we saved from the previous product must be added on, making the total \[15 + 1 = 16\]\[\]. Nothing else needs to be done.

One Digit Multiplication:

We are familiar with how to multiply one 1-digit number by one more 1-digit number. The multiplication table for the relevant integer is used when multiplying one-digit numbers.


Let's say we need to multiply 6 by 4 and we arrange the numbers in a column.

Multiplication


To determine that 6 times 4 are 24, we must mentally read the multiplication tables of 6.

24 is listed as a product. We state that 6 times 4 equals 24.

In this case, the multiplicand is 6, the multiplier is 4, and the multiple fact of the product is 24.

The numbers 6 and 4 are frequently referred to as the 24's component.


Multiplication with Zero:

Zero has an additive identity because it can be added to any number without changing its identity. The zero property of multiplication states that the product of multiplying a number by zero is always zero. Because the zero can come before or after the number, the position of the zero has no effect on the property.


So, \[5 \times 0 = 0\]. The zero property of multiplication applies to all numbers, including integers, fractions, decimals, and algebraic terms.

As a result, zero times any numerical digit equals zero.

Solved Examples(One Digit Multiplication Worksheets) :

1: What will 9 times 7 equals ?

Ans: 9 times 7 can be written as :

\[9 \times 7=63\]

9 times 7 equals 63.


2: Find the value for 0 * 0.

Ans: The value for 0 * 0 will be 0.

As we know that if we multiply any number (here it is 0) with 0 we will get 0.


3: If a child gets 8 chocolates every day, then how many chocolates will he have in a week?

Ans: We know that 1 week \[ = 7\] days

And child gets 8 chocolates every day

Means after 1 week he will have \[8 \times 7\] chocolates .

\[8 \times 7=56\]

After 1 week he will have 56 chocolates with him.


Conclusion :

Mathematical multiplication is equivalent to adding equal groups. As we multiply, the number of things in the group increases. The product, the two factors, and the product are the three components of a multiplication problem. Multiplication is represented by the symbol "✖".

FAQs on 1 Digit Multiplication Explained for Students

1. What is 1 digit multiplication?

1 digit multiplication is the process of multiplying a number by a single-digit number (0–9). It means finding the total when one number is added repeatedly a certain number of times.

  • Example: 4 × 3 = 12
  • This means 4 added 3 times: 4 + 4 + 4 = 12
  • It is one of the basic operations in arithmetic and forms the foundation for multi-digit multiplication.

2. How do you multiply a number by a 1 digit number?

To multiply by a 1 digit number, multiply each digit of the number by the single digit and add any carry if needed.

  • Step 1: Write the numbers vertically.
  • Step 2: Multiply the ones place.
  • Step 3: Carry over if the product is 10 or more.
  • Example: 23 × 4
    4 × 3 = 12 (write 2, carry 1)
    4 × 2 = 8 + 1 = 9
    Final answer: 92

3. What are the multiplication tables for 1 digit numbers?

Multiplication tables for 1 digit numbers list the products of numbers from 1 to 9 multiplied by other numbers.

  • Example from the 5 times table:
  • 5 × 1 = 5
  • 5 × 2 = 10
  • 5 × 3 = 15
  • 5 × 4 = 20
Learning these basic multiplication facts helps in solving 1 digit multiplication quickly and accurately.

4. What is an example of 1 digit multiplication?

An example of 1 digit multiplication is 7 × 6 = 42. This means adding 7 six times: 7 + 7 + 7 + 7 + 7 + 7 = 42.

  • Single-digit numbers are between 0 and 9.
  • The result of multiplying two 1 digit numbers can be one or two digits.

5. Why is 1 digit multiplication important?

1 digit multiplication is important because it builds the foundation for long multiplication, division, fractions, and algebra. Without knowing basic multiplication facts, solving larger math problems becomes difficult.

  • Used in daily life (money, measurements, shopping).
  • Helps improve mental math skills.
  • Supports learning of multi-digit operations.

6. What happens when you multiply by 0 or 1?

When you multiply any number by 0, the result is 0, and when you multiply by 1, the number stays the same.

  • Example: 8 × 0 = 0
  • Example: 8 × 1 = 8
  • These are known as the zero property and identity property of multiplication.

7. What are the basic properties of 1 digit multiplication?

The basic properties of 1 digit multiplication include the commutative, associative, and distributive properties.

  • Commutative: 3 × 5 = 5 × 3
  • Associative: (2 × 3) × 4 = 2 × (3 × 4)
  • Distributive: 4 × (2 + 3) = (4 × 2) + (4 × 3)
These properties make multiplication easier and more flexible.

8. How do you solve 2-digit by 1-digit multiplication?

To solve 2-digit by 1-digit multiplication, multiply each digit of the 2-digit number by the single digit and carry if necessary.

  • Example: 34 × 3
  • 3 × 4 = 12 (write 2, carry 1)
  • 3 × 3 = 9 + 1 = 10
  • Final answer: 102
This method is called the standard multiplication algorithm.

9. What are common mistakes in 1 digit multiplication?

Common mistakes in 1 digit multiplication include forgetting to carry and mixing up multiplication facts.

  • Not adding the carry to the next digit.
  • Confusing tables (for example, 6 × 7 incorrectly).
  • Writing digits in the wrong place value.
Carefully checking multiplication tables and place value helps avoid these errors.

10. How can I practice 1 digit multiplication easily?

You can practice 1 digit multiplication by regularly reviewing multiplication tables from 1 to 9 and solving short drills daily.

  • Use flashcards for quick recall.
  • Practice timed quizzes for speed.
  • Solve word problems like: If one pencil costs $3, what is the cost of 5 pencils? (3 × 5 = 15).
Consistent practice improves accuracy and mental math skills.
