Multiplication can be thought of as repeated addition, or as objects in a group. 

 means adding  ten times. 

 and 

Or we can think of this as grouping objects. We have  groups, with  objects in each group. We can count up the total number of objects, in this case triangles. 

Multiplication can be thought of as repeated addition, or as objects in a group. 

 means adding  nine times. 

 and 

Or we can think of this as grouping objects. We have  groups, with  objects in each group. We can count up the total number of objects, in this case triangles.

When multiplying, we multiply the ones digit with the ones digit followed by tens digit with ones digit.

So  is .

The  is in the oens digit and we carry the  to the tens digit. 

 but since we carried a , we need to add that. .

Our final answer is .

When multiplying a pair of two digit numbers,  will be multplied by  first, followed by .

So then,  is . The  is in the ones digit and we carry the .

Next,  but we need to add the  which makes .

Now, when we multiply  we get .

We put this  underneath the  because we are multiplying  in the tens position.

Finally, . We now add. The  is brought down.

Next, . The  is in the tens position and the  is carried over.

We have  to represent the hundreds position.

Our final answer is .

So then,  is . The  is in the ones digit and we carry the .

Next,  but we need to add the  which makes .

Now, when we multiply  we get .

We put this  underneath the  in the tens column because we are multiplying  in the tens position.

Finally, .

We now add. The  is brought down. Next, .  

We have  to represent the hundreds position.

Our final answer is 

The power of  tells us how to move our decimal. Because we have a positive  power, we move our decimal over  places to the right.
