Over time some things may change,
Whilst all the others remain the same.
A mountain standing as steady as can be,
Only seems unmoving to you and me.
Things not at first readily seen,
You may upon closer inspection glean.
The words will sometimes lie,
But on numbers you can always count by.
If this may tend toward the awkward at times,
It's not due to difficulty trying to rhyme.
As usual, don't go about this the usual way,
B/c by not the usual rules can I play.
Albeit this creation was indeed very tedious to make,
May solving it by comparison only be a piece of cake,
What am I?
