60 secounds To me i think the calculator invented by william seward burroughs in 1893 it was invented to do math in a faster way. it changed lives because it made work a lot faster. it replaced a nomal pencil and paper. the biggest change was it made a six hour job a one hour job it changed the future because it made science a lot easiewr and a faster easier way to made medience and find cures for a lot more quicker. it changed my life because my math homework takes 30 minutes not 3 houps because the calculator does ther math work for you and you need to just right it down. first is the nomal ones they used in the 19 centery. they used the old nomal one and it had + - / * that is it the power was a baddery. then they masde a soler one thgat made it so that you can use it all places thaT there is sun and that is all most all places and then a lot of pedople started to buy it. then now a days you have a caulater on your compter and it has a lot more futers in it did before and it looks a lot better and is a lot easier to use.
