Subjects learnt by Margie and Tommy

Margie and Tommy, the two children in the story "The Fun They Had" by Isaac Asimov, learnt various subjects through their mechanical teacher.

English
The mechanical teacher taught them English, which included grammar, vocabulary, comprehension and composition. Margie's mechanical teacher was more advanced and could read stories aloud, whereas Tommy's was older and could only display words on a screen.

History
The mechanical teacher also taught them history, which included dates, events and important figures from the past. However, the children found this subject boring as they had to read from a screen instead of experiencing it.

Geography
Geography was another subject that the mechanical teacher taught the children. They learned about different countries, their capitals, and their geographical features.

Arithmetic
The mechanical teacher also taught arithmetic, which included addition, subtraction, multiplication and division. The teacher provided instant feedback on the children's answers.

Spelling
Spelling was another subject that the mechanical teacher taught. The children had to spell words correctly and the teacher would correct them if they made any mistakes.

Science
The mechanical teacher also taught science, which included topics such as anatomy, biology and physics. The teacher used diagrams and animations to explain complex concepts.

Overall, the mechanical teacher taught the children a wide range of subjects, making their education comprehensive and well-rounded.
