Replace the letters with digits (the same letters represent the same digits):
MATH*9=HTAM

Step-by-step explanation:

Now,

where the small letters a,b, c and d refers to carried numbers.

Converting this to equations:

This equation comes from carrying remainders.

We know because H is a single digit, so by the fourth equation,

9M+b=H

M=0 or 1 since any larger integer value of M will make H a double digit number.

If M=1, we have:

The only multiple of 9 that will give a remainder of 1 is 9. Therefore:

In this case, H=9

However, even if A and T were to be 0, the least possible number

1009 X 9= 9081

Therefore:

M=0

And sure enough

-232
