Solving cryptarithmetic problems

Question

I was recently trying to solve cryptarithmetic problems like:

       F Y H
     * E W T
     -------- 
     Z E T F
   E K Z Z
 Y Z T X
 ------------
 Y F Y W E F

But I am failing repeatedly to get the hang of such problems.I start solving problems but then I cannot get the intuition of such problems.How should I practise to master them?Any good resources in this regard?

Answer 1

     8 4 6
    *5 7 3
  ----------
   2 5 3 8
 5 9 2 2

4 2 3 0

---

4 8 4 7 5 8

---

where F=8, Y=4 H=6 E=5 W=7 T=3 Z=2 K=9 X=0
