In the given text, there are several errors:

1. "The knowledge of the natural numbers are preserved": The verb "are" should be changed to "is" to agree with the singular subject "knowledge."

2. "it is the older than any surviving written text": The word "the" should be removed before "older" to make it grammatically correct. Additionally, the word "the" should be added before "surviving."

3. "One way to see the development of the assorted number systems of modern ...": The sentence appears to be incomplete and lacks clarity. It could be improved by providing more context or completing the thought.

To spot these errors, you can read the text carefully and pay attention to subject-verb agreement, article usage, and sentence structure. Proofreading and reviewing your work can help identify common mistakes and improve the overall quality of your writing.
