100blocks... This software can be learned only by mouse operation. There is a device of the screen for children, a music, the sound effect when inputting, etc. It is said that "100 Blocks calculation" is solving the same problem repeatedly rather and contracting the lapsed time rather than solving the problem which is different each time, and calculation capability raises it more.
By repeating the problem same each time by the [Number lock function], it can be learned like study with the print performed in school.
