1 + 1 - 9 + 100 x 3 - 20
1 + 1 - 9 + (100 x 3) - 20
1 + 1 - 9 + 300 - 20
Then just work from left to right.
Should be 273.

273
Assuming you use the PEMDAS method and go left to right.
1) 100 x 3= 300 (no parenthesis or exponents, move on to multiplication)
2) 1+1=2
3) 2-9=-7
4) -7+300=293
5) 293-20=273
It's been a while for me, but that's my answer on it.
