Hi….

Personally for me, I find that multiplying with more than one digit is easier when the numbers are written vertical rather than horizontal.  For example, it’s easier to solve

   25
X 38 ‘
______

.than 25 x 38

Also another trick that I use is when there’s a number that ends in zero, put that number at the bottom.  For example,

   27
X 30
_______
 810

But if you put the 30 on the then you must do
    30
  X 27
       ________
   210
          60  
        __________
           810

Hope this helps!
