Abstract: "Five monkeys divide Peach problem" is a very famous in and out of the interesting math problem. The simple method of calculating this type of problem has plagued some large physicists and mathematicians. Dr. T.D. Lee a lecture at the Chinese University of Science and Technology, and also specifically mentioned this question, Through the analysis of this problem, this paper deduces the simplest general solution Formula y=a (a/m) n-1-db/c,

Definition An array is a set of units or a set of processed values. If you write an array-based formula, that is, an array formula, you can use this single formula to execute multiple input operations and generate multiple results. Each result is displayed in one unit. . Array formulas can be considered as formulas with multiple values. The difference from a sing

① error value: # # # # # # # # Meaning: The data entered into the cell is too long or the result of the cell formula is too large to make the result appear in the cell. or the date and time format of the cell to do subtraction, there is a negative value. Workaround: Increase the width of the columns so that the results can be fully displayed. If a negative value is caused by a date or time subtraction, you can change the format of the cell, such as
