Multiplication is a basic arithmetic operation that involves repeated addition of the same number. It is represented using the symbol "x" or "•". When you multiply two numbers, you are finding the total of adding one number to itself the other number of times.
Here's an example to help you understand multiplication: If you have 3 groups of 4 apples, you can find the total number of apples by adding 4 + 4 + 4, or by multiplying 3 by 4 (3 x 4 = 12). So, 3 groups of 4 is the same as 3 times 4, which equals 12.

There are several important properties of multiplication:
Memorizing multiplication tables can help you quickly solve multiplication problems. Here is a basic multiplication table:
x | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
1 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
2 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | 20 |
3 | 3 | 6 | 9 | 12 | 15 | 18 | 21 | 24 | 27 | 30 |
4 | 4 | 8 | 12 | 16 | 20 | 24 | 28 | 32 | 36 | 40 |
5 | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 |
6 | 6 | 12 | 18 | 24 | 30 | 36 | 42 | 48 | 54 | 60 |
7 | 7 | 14 | 21 | 28 | 35 | 42 | 49 | 56 | 63 | 70 |
8 | 8 | 16 | 24 | 32 | 40 | 48 | 56 | 64 | 72 | 80 |
9 | 9 | 18 | 27 | 36 | 45 | 54 | 63 | 72 | 81 | 90 |
10 | 10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 | 90 | 100 |
When multiplying larger numbers, use the long multiplication method to find the product. Here's an example:
Find the product of 23 and 15:
23 x 15 ------ 115 (23 x 5) + 345 (23 x 10, shifted one place to the left) ------ 345 (Partial products added together to get the final product)
