算盘进行加减运算,比小型电子计算机快,而小型电子计算机进行乘除运算,又比算盘快。能否各取其长、互避其短,设计一种新型计算工具?今年三月,经中国珠算协会集体研究,设计制造成功了这种理想的新型计算工具——电子算盘。电子算盘的上半部是微型集成电路,下
Abacus addition and subtraction operations, faster than small electronic computers, and small electronic computer multiplication and division operations, but also faster than the abacus. In March this year, the Chinese abacus Association collective research, design and manufacture of this ideal new computing tools - electronic abacus. The top half of the electronic abacus is a miniature integrated circuit, under
