Multiplication as Repeated Addition

Look at these sets of pencils. Each set has four pencils.

4 + 4 + 4 = 12

Three sets of 4 make 12.

Three 4s are 12.

When we add the same number again and again, it is called repeated addition.
Instead of adding the same number again and again, we can multiply to fi nd out

the total number of pencils.

Repeated addition of the same number is called multiplication. The sign of

multiplication is ‘×’. 3×4

For the above example, we write 3 × 4 = 12. The answer we get

We read it as three times 4 is 12 on multiplication is
called the product.
or 3 multiplied by 4 is 12.

The result 12 is called the product.
