Experience the application of scientific counting method and approximate number in practice, and talk about the function of scientific counting method and approximate number

The scientific counting method is a conventional method for the convenience of writing and memory simplification of long numbers in practice. Approximate numbers are very different from the actual numbers, but there are differences. It is also to simplify writing. Approximate numbers are similar numbers (obtained by rounding off) on the basis of real data, and some are recorded by scientific and technological methods, all for convenience
This is my understanding. I hope it can help you

How many minutes and seconds are there in 36 hours
