## How to use Standard algorithm to solve multiplication expression?

Standard algorithm multiplication PDF worksheets & examples introduce some examples to well understand the method and several printable worksheet for training. For this example, you’ll see how to multiply a 3-digit number with 2-digit number using standard algorithm multiplication.

### Multiply 259 x 63

#### Step 1

Set up the problem with bigger number on top.
Multiply ones digit of bottom number by the ones digit of the top number (9 x 3 = 27).

If answer is more than 10, write the ones digit below the ones digit of the number and place the tens digit of answer over the tens digit of top number.

That is 7 for ones and you carry 2. #### Step 2

Next multiply the ones digit of the bottom number by the tens digit of top number.
If you carried a number, add it to your answer. For this example, you have (5 x 3 = 15) plus the carried number (2). That is 15 + 2 = 17.

Write the ones digit (7) of the answer to the left of ones digit from first step.

If there is a tens digit, carry it over to the next digit of top number. Here you carry 1. #### Step 3

Continue to multiply the ones digit of the bottom number through the remaining digits of top number. Carry over when you have to.

So, you have 3 x 2 = 6. Then you add the carried number from step 2.

That is, 6 + 1 = 7 #### Step 4

Now, repeat the process with the tens digit of bottom number.

But first write a zero in ones place, to remind yourself that you are multiplying by tens. #### Step 5

Multiply the tens digit of the bottom number by each of the digits in the top number.    #### Step 6

If the bottom number has more digits, repeat the above step, but make sure you add zeros to remain yourself.
