19. The largest number in a group of numbers






20. Any whole number that ends with 0 - 2 - 4 - 6 - or 8 - any whole number that can be divided by 2






21. A property of real numbers that states that the sum or product of a set of numbers is the same - regardless of how the numbers are grouped - (a+b)+c=a+(b+c) - e.g. (1+2)+3=1+(2+3)
