Multiplying 2-Digit Number by Single Digit Number
Basic Concept of Multiplication
When we add same number multiple times, then it is known as repeated addition. Multiplication is nothing but the repeated addition.
Symbol of multiplication is '×'
We have 3 balls in 3 groups.
So total number of balls = 3 + 3 + 3 = 9
We have 2 suns present in each group and we have 4 groups as shown in the above figure.
So total number of suns = 2 + 2 + 2 + 2 = 8
Order in Multiplication
If we change the order of the numbers we are multiplying, the result remains unchanged.
2 groups of 3 = 2 × 3 = 6
3 groups of 2 = 3 × 2 = 6
So, 2 × 3 = 3 × 2 = 6
Let us take one more example
4 groups of 2 = 4 × 2 = 8
2 groups of 4 = 2 × 4 = 8
So, 4 × 2 = 2 × 4 = 8
Multiplying by 2
1 group of 2 smileys = 2 2 groups of 2 smileys = 4
3 groups of 2 smileys = 6 4 groups of 2 smileys = 8
5 groups of 2 smileys = 10 6 groups of 2 smileys = 12

Single Digit Multiplication
We can perform multiplication in two ways, they are shown below.
Multiplying 2-Digit Number by Single Digit Number
1. Write both the numbers according to the place value
2. Bigger number should occupy the upper row as shown below
3. Multiply the digits present in ones place first
4. Multiply the digits present in tens place
Example 1. Multiply 13 by 2.
Solution. Write both the numbers in tabular format as shown below.
Multiply the digits present in ones place (3 × 2 = 6). Write the result in ones place as shown below.
Now, multiply the digits present in tens place (1 × 2 = 2). Write the result in tens place as shown below.
So, the result is 26.
