Life without calculators
[1] If we didn't have calculators, how different life would be? Well the scientific calculator only exist for more than 40 years at most, it seems like it's too much time, but actually it isn't, and not every person had the money to buy it. If we go back in time, people used to use abacos, it is a tool that you use to do manual calculations, but even before people had this, obviously they used to do a lot of operations in paper, maybe like, as it was normal for them it didn't bother them, but I think it was more complicated and tedious. [2] Well, if we didn't have calculators, It hink it would be more complicated, but like I said, if we get used about this, maybe we could sharpen our mind and do operations faster than we expected, and when we don't have a calculator near of us, it would be easy for us to make operations, at first like we were used to useing calculator, maybe it would be difficult to leave it, but I think our mind is powerful enough to deal wit...
