Happy Hump Day! Time to get your riddle exercise on 🙂

Brothers four they quarreled long,

Each one claimed the others wrong.

And so they left that neutral site,

One up, one down, one left, one right.

 

Explorers now their vectors steal,

Affix them to a tiny wheel.

A priceless bargain, bar the cost

Feels the force, and aids the lost.

 

Same as before if you know the answer post your guess in the comment section below, when the correct answer is posted I will confirm! 😉
