Multiplication is a way to find out how many things there are when you have the same number of things repeated a certain number of times.
Think of it like having a row of blocks. If you have 4 blocks in a row and you repeat that row 3 times, you can use multiplication to find out how many blocks you have in total.
Here's an example:
4 x 3 = 12
The answer, 12, is the total number of blocks you have when you multiply 4 and 3.
The symbol x is used to show multiplication. You can multiply as many numbers as you want, just keep multiplying one number by the next! With a little practice, you'll be multiplying like a pro!
