Are you an Einstein?

Question

Hey everyone! Can you give me 3 solutions to this, and tell me if it was hard or easy? I found it on line and I was wondering about it. But no solutions,no best answer. Here's the article:

Albert Einstein was bright, even as a child. It is reported that when he was six years old, someone asked him if he could place plus and minus signs between the digits

1 2 3 4 5 6 7 8 9

so that the answer on the right would be 100. The digits had to appear in consecutive order.

Allegedly, Einstein wrote out:

1 + 2 + 3 - 4 + 5 + 6 + 78 + 9 = 100

Which was a correct solution. Can you find any other solutions?

That was the article! Don't you think that he was really smart? Weird, isn't it?

Answer 1

in a response to the initial question yes yes i am an Einstein

thank you

Answer 2

I know he was A GENIUS. I'm don't know if I'm one.

Answer 3

123 + 4 - 5 + 67 - 89 = 100

123 + 45 - 67 + 8 - 9 = 100

123 - 45 - 67 + 89 = 100

my name's not Einstein. my parents named me H-----. but friends call me Kimmie.

Answer 4

One solution found:

  -1+2-3+4+5+6+78+9
