We can use the method of counting zeros to multiply a number that ends in zero by another number.
For example, to find we first figure out the non-zero parts:
We can see that the first number has a block of zeros containing zero only.
Next, we multiply the non-zero parts:
Finally, we join this product with the single
Therefore,
What is
First, we figure out the non-zero parts:
We can see that the second number has a block of zeros containing zero only.
Next, we multiply the non-zero parts:
Finally, we join the above with the single :

We can use the method of counting zeros to multiply a number that ends in multiple zeros by another number.
To illustrate, let's multiply First, we figure out the non-zero part and the block of zeros for both numbers:
We can see that the second number has a block containing zeros in total.
Next, we multiply the non-zero parts:
Finally, we join the above with the block of zeros:
Therefore,
What is multiplied by
First, we figure out the non-zero part and the block of zeros for both numbers:
We can see that there are zeros in total.
Next, we multiply the non-zero parts:
Finally, we join the above with the block of zeros:

We can use the method of counting zeros to multiply two numbers that both end with zero.
For example, to multiply by , first, we figure out the non-zero part and the block of zeros for both numbers:
We can see that there are zeros in total.
Next, we multiply the non-zero parts:
Finally, we join the above with the block of zeros:
Therefore,
A baker bakes muffins, each with blueberries inside. How many blueberries are there in total?
To calculate the total number of blueberries that the baker used, we need to multiply by
First, we figure out the non-zero part and the block of zeros for both numbers:
We can see that there are zeros in total.
Next, we multiply the non-zero parts:
Finally, we join the above with the block of zeros:
Therefore, the baker used a total of blueberries to bake the muffins.
