How To Multiply Numbers # 2
We've seen here one
way to multiply numbers. Another similar,
but quicker way to do multiplication calculations involves regrouping
and carrying forward. The examples on this page show how this
can be done.
Note: Try your own numbers in the Multiplication Calculator for
a step through of the method that is illustrated below.
Check out this multiplication worksheet generator to help practice multiplication. You can set up your own type of question by selecting a range of values for both numbers and you can randomly generate any number of practice questions.
Multiplication  another way (regroup and carry forward)
318 x 6 = 
Multiply the ones
6 x 8 = 48 

Write the 8 in the ones' place and carry the 4 forward
to the tens' place 

Multiply the tens
6 x 1 = 6 and add the 4 that was carried forward
6 + 4 = 10 

Write the 0 in the tens' place and carry the 1 forward
to the hundreds' place 

Multiply the hundreds
6 x 3 = 18 and add the 1 that was carried forward
18 + 1 = 19 

Write the 1 in the thousands' place and the 9 in
the hundreds' place 

318 x 6 = 1908 
Notice that in the example below there is one step that does not require
regrouping and carrying forward.
403 x 7 = 
Multiply the ones
7 x 3 = 21 

Write the 1 in the ones' place and carry the 2 forward
to the tens' place 

Multiply the tens
7 x 0 = 0 and add the 2 that was carried forward
0 + 2 = 2 

Write the 2 in the tens' place (note: there's
nothing to carry forward in this case) 

Multiply the hundreds
7 x 4 = 28 

Write the 2 in the thousands' place and the 8 in
the hundreds' place 

403 x 7 = 2821 
Check to be sure your child knows that regrouping
and carrying forward is often not required for some, or all the
steps when using this method of multiplication.
