Oral arithmetic superman

The predecessor of "Superman of Oral Calculation Integrated Edition" is "Superman of Divine Calculation". Considering that it is easier for friends to search and compare and understand the content of the software more intuitively, the name is hereby changed. Different from similar oral arithmetic practice software, this software is suitable for use by people of different age levels from primary school to adults, and is especially suitable for use by friends with an education level of junior high school or above. The exercise form is lively and lively, and the content includes addition, subtraction, multiplication, and division. It is suitable for the traditional four arithmetic operations of preschool and elementary school. It is also suitable for those with elementary education levels such as exponentiation and square root, as well as those with high school education level and above such as factorials, solving quadratic equations, permutations and combinations. The software allows you to freely choose exercises or contact randomly. It has functions such as self-set question volume, time limit for doing questions, different difficulty levels, and penalty for wrong questions to strengthen practice. It can also be controlled by computer processes to improve practice efficiency and conduct intensive practice. All features can be customized. The practice format is flexible. During the practice, each question uses countdown, human-computer dialogue and lively sound effect prompts. You can improve your oral arithmetic speed and mental arithmetic ability in a relaxed yet exciting environment. This will train you for life. With your rapid calculation skills, I wish you to become a new generation of verbal calculation superman.
"Verbal Superman Integrated Edition" is the final version. When I originally wrote the software "Calculation Man", I was about to enter college and start learning a new programming language. This is a work from my high school days, so let it be fixed here with the memories of my high school years. So when I am about to enter the university campus, I once again update this small work and present it to everyone. With this starting point, I am confident that I will be able to go further and more steadily when I am about to start college. At this time, I would also like to give it as a small parting gift to all the teachers and friends who have cared for me for ten years.
Today, the author has entered university. Due to the change in professional direction, I left the career direction of pure software development. I thought that there are many small mathematical programs of great practical value left behind, such as "Equation Solver", "Equation Solver" and "Equation Solver". There are more than ten practical gadgets such as "Sequence Previewer", "Permutation Combination Number Calculator", "Prime Number Program", "Three-Sided Triangle Solution", etc. Some of them were written when I was studying programming in college for one year. I hope to communicate and share with everyone, so I consider updating this "Verbal Arithmetic Superman" and combine these useful small programs and oral arithmetic practice software into a more powerful and practical software. Dedicated to everyone, so this may be the last update.
And my fellow users and I may not be able to meet each other even if we meet by chance. Maybe when I wrote this software, I have already gone through the path that you are going to go. Maybe we are just the same age, or maybe I am just the little brother. But no matter what, my high school years brought me so many memories, and I have no chance to go through them again. I will continue to work hard on my way to college. Finally, thank you for using it. I hope this little software can bring you happiness and profit, and I also hope you will recommend it to your friends. May you who are about to face a turning point in your life, or are just starting out in life, leave a smile of victory after every moment.
