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.
For example, if we multiply $$2 × 4$$ we get $$8$$, but how we get it?

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 $3×4$.

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.
