Vertical Multiplication

Learn the multiplication tables thoroughly and follow these rules:

First rule

Write down the exercise correctly: The ones under the ones, the tens under the tens, and the hundreds under the hundreds.
The number with more digits will be written above the one with fewer digits.

Second rule

When the product is greater than 99 it is stored at the top left and must be remembered to add it to the next result.

Third rule

Before moving on to multiply the next digit, the "numbers stored" at the top left must be erased to avoid confusion.

Fourth rule

We will add a 00 below the result to indicate that we have moved to the next digit, each row of results will start one place to the left in relation to the previous row.
