Here is one last puzzle on digit arrangements for the end of the quarter. Obtain 100 using the digits 1 through 9 in order and the operations of addition, subtraction, and juxtaposition only. For example, one solution is 123+4-5+67-89=100. Note that the digits must be in order and that only +, -, and the placing of digits side by side to create base 10 numbers are allowed operations. There are a total of 11 more ways to create 100 in addition to the one just given. Find as many as you can.
