its prob true, think about it if you were born in 1990 you would be 17-18 right now, you would have been 8-10 when computers got huge and have prob used one every day in school or at home for homework, you simply arnt asked to do things by hand anymore, literally everything from about 6th grade on is done with a calc provided its not a big long equation you need to factor, i used to sub at my local school alot all kids 9-12 have a TI83 or better and most primary schoolers have a normal calc to do work with, sad possibily, unexpected no, technology makes things easier, puching buttons is easier then thinking
hell im 26 and have a degree in physics and work as an engineer and i can not do long division by hand, because i havent don it in 8 years, 1st day in college we used a calc or a comp for everything, hell we even had large equation tables where we would just look shit up
