multiplying tens, hundreds and thousands

Today we are talking about multiplying by 10s 100s and 1000s,
Here Is a equation we have set out ( 93 x 4 ) To start of you have to find out the answer basically anyway you want, once your finished that you should have a answer and for this equation the answer is ( 372 )
To start of we are starting of with 93 x 40 =
There is 3 steps to this method of doing it,
First you write 93 x 4 x 10 = Then make a new sentence starting with the equal sigh, All you have to do is break it down by going 93 x 4 = 372 as we know then you would go 372 x 10 = because you are x 93 by 40 which is in the 10s, anyway make a new line going 372 the answer but remember we have to x it by 10 so all you have to do is x the numbers together. To add this all you do is add the 0 to the number which is 372 + the 0 = 3720.
Same with all the others if you are multiplying by 100 ( 93 x 400 ) and the two zeros two the number which would be 37200, same for the 1000s as well as the 1000s.
