### Theory:

**Multiplication:**

We know that addition is an increasing quantity and subtraction is an inverse of addition that is decreasing quantity, but what about multiplication?

Remember that multiplication is a continuous addition.

We received \(8\) in answer by continues addition of \(2\) by \(4\) times.

That is \(2 + 2 + 2 + 2 = 8\).

Therefore now you understood that multiplication is nothing but a continuous addition.

Now we will how to multiply the number using a number line.

**Multiplication on number line:**

Now let's see the multiplication of any two whole number on a number line.

Assume that we have to find $3\times 4$.

**We can find this using the following steps:**

**1.**We should start from \(0\), then move \(3\) units at a time to the right side of the number line.

**2.**Then make such \(4\) moves, because the multiplier is \(4\) then we will reach \(12\).

**Therefore we get**\(3 × 4 = 12\).

**Applying this method, we can easily find the value of the multiplication of two number.**
