the Advantages And Disadvantages of A Calculator
As we all know,there are advantages and disadvantages with everything.The invention of calculator has brought advantages to us,but it also has many disadvantages.According to a survey made by some experts,the calculating ability of the students of middle and primary school now has decreased a lot than that ten years ago.What causes the problem?We can obviously see that the calculators have made it.The students rely on the calculators so much that they don't use their brains when they do the maths exercises.So day by day,their calculating ability decreases.
In my opinion,in order to have good calculating ability,we're supposed to use our brains instead of a calculator.
