Many of the models of calculators are an auto turn off; one who is working has to keep the calculator non-operating for a few seconds to turn it off, and some can be switched off by closing their lid. Some of the calculators are provided with the power off button. The displays of Calculators are liquid crystal displays. Some of the modern calculators are provided with memory cards and make the calculator able to store data. The storage capacity can be increased by putting the memory cards with large storage space. Initially many of the schools allowed their students to use calculators for solving their mathematical problems but many of the parents and teachers opposed this idea of allowing calculator in schools because they thought that the students will then totally rely on calculators. There was an agreement made that the students will be allowed to use the calculators only after when they attain proficiency in solving the sums themselves. After a brief research it was proved that calculator restrict the mathematical thinking power of the children’s and lack mathematical problem solving skills. hydro electric hydro electric power what is hydro electric inventhistory power generator wind power generator solar and power electric transportation Visit the website and get more information => www.inventhistory.com
