10 multiplied by 13 is 130. A trick is to just take the zero away and multiply 13 times 1, and then after you do this you add the zero back on. 130 divided by 130 is 1. You can do the same kind of trick for this, just when you are done, you do not add the zeros back in.
10 x 13 = 130 
You can find this by adding 10, 13 times 

Looking like this: 10+10+10+10+10+10+10+10+10+10+10+10+10= 130 

Or, another simpler way would be to multiply 1 x 13 = 13 and then add the number of 0's that are in the equation, which there is only one, so we then get 130!

Hope this helps!
