On the application and function of calculator Choose any three digit number (requirement: the number of hundreds is at least 2 times larger than the number of ones), invert the order of the number of hundreds, tens and ones to get another three digit number, subtract the smaller three digit number from the larger three digit number, invert the order of the numbers of the difference to get another three digit number, and add the difference itself to the three digit number, What's the result you got? Try a few more numbers. What do you find? Choose any four digits and follow the rules above. What will you get? What if you choose any five digit number Select any positive number and perform the following operations: add L, then take the reciprocal, and continuously perform the above operations according to the obtained results What did you find? If you change the operation rules (such as "add 2, then take the reciprocal..." Square plus one, then square and take the reciprocal "...) Will we find a similar pattern? With the help of your calculator, get the cycle section separately If a number key (such as 3) on the calculator is broken, how to calculate the formula containing the number? (such as 2 + 3, 34 12, 3 × 49325413,...) What if an operator key is broken? The problem in brackets is 2 + 3,34-12,3 × 49325 △ 413
