Can you do the math：What is one hundred times four，divided by the square root of a hundred? How can you work it out quickly?
The answer is forty．Years ago，three scientists at Texas Instruments，Jerry Merryman，James Van Tassel and Jack Kilby，invented the handheld electronic calculator．Their first device could add，subtract，multiply and divide and it was small and easy to take．
Yet after forty years，calculators in the classroom still add up to the same old debate Generally calculators are considered to be useful——especially with more complex math．Some math teachers at every level support the use of calculators and students are even permitted to use them when they take college entrance tests．But it is also thought that young students should know basic calculation before they begin using them．
Some education experts think calculators are used too much. Children，they say，learn to depend on these electronic brains instead of their own．Calculators may not only give students answers to questions they do not really understand，they may also keep them from discovering ideas for themselves．
Other experts，though，say calculators have helped make mathematics more understandable to more students．They say calculators give students more time to understand and solve problems，and to develop a better sense of what numbers mean．That way，the reasoning goes，they can feel better about their abilities．
1．Which of the following calculation agrees with the question raised in the 1st paragraph?
A．
