The Block Challenge

There are several ways to come up with the number 100 by using each of the digits 0 through 9 exactly once. Here are two examples: 100=0 + 1+2+3+4+5+6+7+(8*9) 100=78+(3/6)+21 + (45/90) Your challenge is in four parts: Parts I and II) Find two ways, different from the ones above, to make 100 by using the digits 0 through 9 Parts III and IV) Find two different ways to make 100 by using the digits 1 through 9 (no 0)
