DECODING LETTERS

Can anybody shed some light on this as how to solve it with equations:





T W O
X T W O
-------------
T H R E E

Re: DECODING LETTERS

I assume it is TWO x TWO=THREE where one letter is for one digit.

First of all please mark that T = 1 (otherwise two numbers T** x T** would NOT equal T****, I mean first digit would not be identical).
Second - THREE is square of TWO.

You wanted some light, is it enough? I mean you need to work yourself, it is maths, i.e. DIY

Assuming different letters represent different digits, and that decimal arithmetic is used, the letter O cannot represent 0, 1, 3, 4, 5, 6, 7, or 9 (since no perfect squares end in 66 or 99), so it must represent 2 or 8, and so E represents 4.

It's now fairly easy to determine what digits O and W represent, and hence what digits H and R represent.

Re: DECODING LETTERS

Why not try to rearrange the problem?

So instead of TWO * TWO = THREE

Try (100T + 10W + 1O)^2.

Find out what that equals and group all of your 10000s, 1000s, 100s, 10s, and 1s together.

After that, try to match them with (10000T + 1000H + 100R + 10E + E).

To start you off, I got 10000T^2 = 10000T, which means T^2 = T. Obviously, T has to equal one.

Edit** Actually... T could be 0 also. This would require H to be 0 as well though. I'm getting answers to fit the format, however my problem is I am ending up with either W equaling T or H equaling T. I can't see another way around this!

I ended up getting T = 1, W = 1, O = 2, H = 2, R = 5, and E = 4. 112*112 = 12544 and 012*012 = 00144

This works great if T and W can be considered the same number, however they are assigned different letters which is confusing me. If someone could please share the correct answer, it would be much appreciated. I'm actually starting to believe it is impossible based on the formula I have.

So O is not 2. However, O = 8 works.
