Simple question.. Use three (+) signs and one (-) sign

Here is a simpple question

Put three + signs and one - sign in the below numbers
to make the sum work

9 8 7 6 5 4 3 2 1 = 100

 

98 - 76 + 54 + 3 + 21 = 100

OMG!! I really did it

 

Awesome that was quick, I thought we have to shuffle the numbers

 

I was just playing with the couple group of numbers and pop up the solution ..

Hey Ziya .. is there only one solution or can be more?

 

That was really quick. I know only one solution, but maybe there should be other solutions too..

 

98 - 76 + 54 + 3 + 21 = 100
9 - 8 + 76 + 54 - 32 + 1 = 100
98 + 7 + 6 - 5 - 4 - 3 + 2 - 1 = 100
98 - 7 - 6 - 5 - 4 + 3 + 21 = 100
9 - 8 + 76 - 5 + 4 + 3 + 21 = 100
98 - 7 + 6 + 5 + 4 - 3 - 2 - 1 = 100
98 + 7 - 6 + 5 - 4 + 3 - 2 - 1 = 100
98 + 7 - 6 + 5 - 4 - 3 + 2 + 1 = 100
98 - 7 + 6 + 5 - 4 + 3 - 2 + 1 = 100
98 - 7 + 6 - 5 + 4 + 3 + 2 - 1 = 100
98 + 7 - 6 - 5 + 4 + 3 - 2 - 1 = 100
98 - 7 - 6 + 5 + 4 + 3 + 2 + 1 = 100
9 + 8 + 76 + 5 + 4 - 3 + 2 - 1 = 100
9 + 8 + 76 + 5 - 4 + 3 + 2 + 1 = 100
9 - 8 + 7 + 65 - 4 + 32 - 1 = 100

 

These solutions are not working. You can use only one time (-) sign , and only 3 times (+)

 

98 - 76 + 54 + 3 + 21 = 100

I've done it in 2 mins without seeing 2nd post
