In this task, we ask you to rewrite a sentence in simple English without changing its general meaning. Essentially, you want to make the sentence easier to read by using simpler words, utilizing more straightforward sentence structures, and omitting non-essential information etc.

Input: Consider Input: In mathematical analysis , the maxima and minima ( the respective plurals of maximum and minimum ) of a function , known collectively as extrema ( the plural of extremum ) , are the largest and smallest value of the function , either within a given range ( the local or relative extrema ) or on the entire domain of a function ( the global or absolute extrema ) .

Output: In mathematics , the maximum and minimum of a function are the largest and smallest value that the function takes at a given point .

Input: Consider Input: Japan 's cadre of highly skilled carrier aircrews with which it began the war were , in effect , irreplaceable because of an institutionalised limitation in its training programs and the absence of a pool of experienced reserves or advanced training programs for new airmen .
