What I want to discuss here is the children should no be allowed to use calculator in early ages they must know the basic rules of math.

I think you will find in most cases that those same children can not use a calculator either. They have not replaced arithmetic, they have dropped it.

I thought that too. But my son (at age 6) showed me another way of looking at it. We had bought him a four function calculator as he was good at basic + - x and รท

Just by playing around with it, he taught himself all the properties of negative numbers. I hadn't planned for that to happen but it showed me that you can use a calculator to help teach things. When we got him a scientific calc, he learnt how to use all the buttons and what they meant. And it happened again when we got him a graphical display calc.

My advice to students when they get a new one, is to spend some time playing around with it to learn all it can do. You can, for instance, learn the rules of BODMAS (BIDMAS) just by doing this.

So I now think using a calculator can help learning if it is used correctly.
