• a Why schools teach mathematics? • b Why is algebra a sort of shorthand?
• c What is the recent advance in mathematics mentioned in the passage ?
• d What can a computer ?
They teach it because it plays such an important part in our lives.
It is a short of shorthand because it can state many mathematical ideas with just a few letters and signs For example, …
It is the building of great electronic computers.
