In This Math Game, How Many Results Can You Get?

You have the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9. You must either place arithmetic symbols or "combine" the digits together so that the resulting number is 100. By "combining" the digits, it means that, for example, 3 and 4 can become 34, or 1, 2, and 3 can become 123. However, the order of the digits must remain the same. How many ways can you make 100?
An example:
1+2+3+4+5+6+7+8 x 9 = 100 
@versatilemole I did hear that game before. But, I literally only found 2 ways

@versatilemole i could give as many solutions as i can to this problem, and then people can add on solutions and count how many ways we can make 100.
