Concepts and calculation

It allows students to concentrate on concepts

There are two aspects to mathematics - understanding the concepts and learning how to calculate with these concepts

Calculation is difficult and the concepts are obscured by the effort required

Concepts can only be used in very elementary situations when students have to do the calculations by hand, otherwise the work required is prohibitive

Allow students to concentrate on the concepts by freeing them from having to do tedious calculations

The ability to look at many more examples and at harder examples can help greatly with understanding the concepts
