**Multiplication**

If we have to add a group of things repeatedly we use multiplication. So multiplication is the repeated addition.

**E.g.**

If a matchbox contains 50 sticks and I have 5 such matchboxes. How many sticks will I have in total including all matchboxes?

We have to add a group of 50 sticks for 5 times :

50 sticks from box 1 + 50 sticks from box 2 + 50 sticks from box 3 + 50 sticks from box 4 + 50 sticks from box 5=50 + 50 + 50 + 50 + 50=250

We can also say 50 **X** 5=250

**"X"** is the symbol of multiplication. The number being repeatedly added (or being multiplied) is called **multiplicand**. The number with we are multiplying or the number of groups is called **multiplier**. The result we get after repeated addition of the group of specified size over a number of counts is called **product**. We can also say that the result we get after multiplying multiplicand and multiplier is called **product**.

**Things to remember:**

**1. **Any number multiplied by zero will give the answer zero.

**E.g. 5 X 0=0.**

**2. **Any number multiplied by 1 will give the same number as the product.

**E.g.** **7 X 1=7**

**3. **The two numbers are multiplied in any order will result in the same product. This is known as the **cumulative property** of multiplication.

**E.g. 3 X 4=12=4 X 3**
