It's computer class.

I'm in a ITC room now, which is near the RAIOSYA , because this time is computer class.

A teacher is sitting in front of students, and teaching the Microsoft Excel.

There are many useful programs in the computer , and Excel is one of them.

I think Excel is very useful to calculate something.

the sum of income , the average of income, for example, is very simply calculated by Excel.

and other complicated calculation is also simply solved if one can treat Excel.

in addition toExcel, There are also useful programs in Microsoft.

For example, PowerPoint is very useful program to present something in front of many people.

So, the ability to treat PowerPoint is required in the place that need presentation.

and also there are many useful programs except this things.

If one use thing useful computer programs, he/she will be able to promote efficiency !
