1 2 3 4 5 6 7 8 9 = 100

This equation is incomplete: 1 2 3 4 5 6 7 8 9 = 100

One way to make it accurate is by adding seven plus and minus signs, like so.

1 + 2 + 3 – 4 + 5 + 6 + 78 + 9 = 100

How can you do it using only 3 plus or minus signs?

123 – 45 – 67 + 89 = 100

123 – 45 -67 + 89 = 100
(1×23)-4+5-6-7+89=100
(1-2+3-4+5)×6-7+89=100
78+9+6+5-4+3+2+1=100
(56-34-12)×(9+8-7)=100
