Maybe a better sensible way to say is,

If you take a number and --multiply it by 10 -- and subtract the result from 143, you値l get three times the original number. What is the number?

Original Number, p.
143-10%2Ap=3p

If you take a number 
Call this original number by a letter, say,

      N

and add a zero to the right 
To annex a zero on the right is to multiply it by 10.

So this is 

    10N

and subtract the result from 143, 
That gives 

   143 - 10N

you値l get three times the original number. 
So we have the equation

   143 - 10N = 3N

What is the number?
   Add 10N to both sides:

     143 = 13N

Divide both sides by 13

     11 = N
