You call these letter problems or cryptarithmetics?

Is that Math?

Anyway, by trial and error, I got

-----,VW

-...*-,GT

_________

-----IW

---VW

_________

---TVW

-----,25

-...*-,13

_________

-----75

---25

_________

---325

Or, G=1, T=3, V=2, W=5, and I=7.

Ist to get is G=1, because G*VW = VW.

Then, by trial and error, T*W could be 6*2, 6*4, 6*8, 3*5, 7*5, or 9*5

That is, W is either 2, 4, or 8 if T=6. Or, W=5 if T is either 3, 7, or 9.

Blah, blah, blah,...

I don't like this kind of Math---if this were Math. I don't go for too much trial and error. It is only guessing, or hit-or-miss. This is computer stuff, spreadsheet stuff, number crunching.

I like Math that is systematic--one thing leads to another, with no too much repititions.

Repititions, number-crunching, and no thinking is mechanical only. For computers only.
