The priority of a calculation is the multiplication and division and then, the sum and the subtraction...So,
2 + 2 x 9 - 8 x 8 x 3 + 6 - 9 =
2 + (2 x 9) - (8 x 8 x 3) + 6 - 9 =
2 + 18 - 192 + 6 - 9 =
-175

First: solve according to order of operations...PEMDAS...>>>
( ), exponents, multiplication, division, addition and subtraction.
2 + 2 x 9 - 8 x 8 x 3 + 6 - 9
2 + 18 - 64 * 3 + 6 - 9
2 + 18 - 192 + 6 - 9
20 - 192 + 6 - 9
-172 + 6 - 9
-172 - 3
-175

Simplify by order of operations (Parentheses, Exponents, Muliplication & Division, Addition & Subtraction). I use * instead of x because its algebra-symbols. The parenthesis, (), show the step performed in the line before.
2+2*9-8*8*3+6-9
2+(18)-8*8*3+6-9
2+18-(64)*3+6-9
2+18-(192)+6-9
(20)-192+6-9
(-172)+6-9
(-166)-9
-175
2+2*9-8*8*3+6-9=-175 (that's Negative 175)

gotta use order of operations...
2 + 18 - 8 X 8 X 3 + 6 - 9
2 + 18 - 64 X 3 + 6 -9
2 + 18 - 192 + 6 - 9
-175 is the answer

2 + 2 x 9 - 8 x 8 x 3 + 6 - 9
= 2 + 18 - 192 + 6 - 9
= 20-198-9
= -187
follow the rule of MDAS (multiplication, division, addition and subtraction)

do all multiplication first, use parenthisis to make it easier...
2+(2x9) - (8x8x3) +6 - 9
2+ 18 - 192+6 - 9
-175 is ur answer!
