8 * 404 = 8(----- + 4)

At first, we will split 404 into two numbers one of them is 4

To find the other number subtract 4 from 404

404 - 4 = 400

8 * 404 = 8(400 + 4)

Now we will multiply 8 by 40 and 8 by 4

8(400 + 4) = 8 * 400 + 8 * 4

It is easy to find the product of 8 and 4

8 * 4 = 32

8 * 400 = 3200

Let us add them

3200 + 32 = 3232

The answer is 3232
