After learning addition, multiplication can be expressed by the sum of multiple identical numbers. After learning multiplication, power can be expressed by multiplication of multiple identical numbers. Logarithms are not difficult to understand after learning multiplication. With logarithm, many problems in astronomy can be solved, and astronomical things can also be solved, and calculus naturally appears. With calculus, it is not difficult to explain the appearance of ordinary differential and partial differential. Having said that, do you think advanced mathematics can improve people's logical thinking ability? The answer is yes. After studying advanced mathematics, you will look at the problem from a different angle, just like learning addition and multiplication.
