The abacus is an easy  to make calculator. I'm entering this in the Technology contest because it saves money because you don't need to buy a calculator and save money and natural ores. Look at the pictures. 
How will it have a part to get 1,000?
As the parts are lower on the abacus their value increases ( row one is the ones, across from it are the fives, it doubles), the 4th row is the thousands ( each piece is 1000. ( sorry for spelling, I'm sure I messed up )
Thank you for commenting.
Its ok.
