Mr Menon reads $12$ pages of the morning newspaper every day. How many pages of the newspaper does he read in a year ($365$ days)?

(i) $4+4+4$ can be written using multiplication symbol as $3\times 4$.

(ii) $3\text{ groups of} 2$ pens can be written as $2+2+2=3\times 2$.

2. Multiplication Tables Using Addition:

(i) To make multiplication tables of $7$, we split the number $7 \text{as} 3+4$

(ii) Now, we can write $7\times 1=3\times 1+4\times 1=7 \text{and} 7\times 2=3\times 2+4\times 2=14$.

(iii) Using the similar process, we can form the tables of $7$

3. Properties of Multiplication:

(i) If we interchange the multiplier and multiplicand in a problem, we get the same product. Example: $2\times 3=3\times 2=6$

(ii) If we multiply zero by a number, we get the product as $0$. Example: $2\times 0=0$

(iii) If we multiply $1$ by a number, we get the product as the number itself. Example: $2\times 1=2$

(iv) To multiply a number by another number ending with $0$, multiply it by number of tens and then add zero in the end to get the product.

4. Multiplication Using Lattice Method:

(i) To multiply $12\times 12$ using Lattice method, first, we split $12 \text{as} 10+2$. Now write the numbers in the table as shown below.

(ii) To get the product, add all the numbers that is $100+20+20+4=144$.

5. Multiplication Using Standard Method:

(i) Standard method of multiplying numbers is used to multiply large numbers.

(ii) To multiply $23 \text{by }4$, first multiply $4\text{ by} 3$ and then $4 \text{by} 2$.
