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

That is very clever

123-45-67+89=100
^_^

Idk that’s how

1+2+3+4+5+6+7+8×9=100

this require a person with above 100 IQ

1 2 3 4 5 6 7 8 9=50
?

1*2+3*4*5-6+7+8-9=100

1+2+3+4+5+6+7+8×9=100

1+2+3+4+5+6+7+8×9=100

@Yared Genene That’s 62.

Thanks to Laquanda and Sjörk, but the riddle asked how you could use only 3 plus or minus signs.

52+39+6-8+7+4×1=100

1 x [ (2×9) + (3×8) + (4×7) + (5×6) ] = 100

I want the answer by using +nd – ….please answer fast…..

123-4-5-6-7+8-9=100

9 – 8 + 7 + 65 – 4 + 32 – 1 = 100
