Hi my name is chaitra so I have a test coming up and I'm having trouble solving three digit by three digit multiplication and two digest by two digit multiplication can you please show me the steps of how to do it with an example

So 2 digit multiplication is like this

   1

  23

x 45

  -----

   115

   920

   -----

1035    

first yo multiply the 5 and the 3 and then you multiply the 5 by the 2 then you will get 15 for the first and you put the 1 on top of the 1 now 5 times 2 plus 1 is 11 so yo put the 11 down at the bottom. now you put a zero at the bottom of the answer will be  

the answer is 37

step-by-step explanation:

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
