From left to right, do multiplication or division first. After that, from left to right again, do addition or subtraction.

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 × 0 = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 0 = 36 1+2+3+4+5+6+7+8+9 \times 0=1+2+3+4+5+6+7+8+0=36

I multiplied 9 by 0 and got 0.

Applying a Gauss Theorem, There were 4 pairs of 9 and I multiplied 4 by 9 to get 36.
