(number) -and/or- (number)~(number) -and/or- (number)~(number)~Decimal -and/or- (number)|(number)~(number) etc...
This entry is a compound entry and is used to provide Maze Makers with the ability to create a number challenge one time and have that challenge present different numbers in the Challenge Text Entry each time a player encounters the challenge.   The Challenge Maze Software uses a pseudo-random selection process to choose which numbers to present to a player based on the this entry.   Then the Challenge Maze Software replaces the NUM's (NUM1, NUM2, NUM3, etc...) in the Formula with NUM's Entry with the selected numbers and performs the indicated mathematical operations to calculate the accepted answer to the number challenge.   To use this entry a Maze Maker builds a series NUM's (separated by a vertical bar '|').   Each NUM created can be an exact whole number or decimal if only (number) is written, can be a possible range of whole numbers if (number)~(number) is written, and can be a range of possible decimals if (number)~(number)~Decimal is written.   For example, if '5~15' is written, a whole number value between 5 and 15 will be used (a value such as 8 or 11).   If '5~15~Decimal' is written, a decimal number value between 5 and 15 will be used (a value such as 8.193 or 11.8145).
