Hi this is my first post here.
On the puzzle ABCD × E = DCBA
Should it not be, (A)(B)(C)(D) x E = (D)(C)(B)(A)
There for A, B, C, D can be anything as long as E = 1 or 0?
If this has been discussed before sorry.

(A)(B) is like (2)(4), which would mean 2x4.
AB is like 24
So if A =2, B = , C = , D = 8, and E = 4, then

Another solution is 1089 * 9 = 9801 provided there is no condition that all the numbers have to be different.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
