2 - 28 x 78 - 89 + d = 34
2 - 2184 - 89 + d = 34
then D = 2305
You follow the order of operations. PEDMAS parentheses, exponents, multiply, divide, add subtract. Therefore it's 2305.

2-28 x 78-89 - d =34
2-28= -26
78-89=-11
-26 x -11 = 286
286 + d = 34
-286 -286
d = -252

d=2,305:
28x78=2,184
so 2-2184= -2182 -89= -2271 +2305 = 34
the reason you get 2305 is because in order to reach at least 0 again you would have to add 2271 just to cancel out the negative. then you would have to add 34 to that to make it go up to 34 get it? so 2271 + 34 = 2305

2minus28 is = to -26 (minus 26)
78minus 89 =11
11 times minus 26 is minus 286
If you had+286 answer would be 0
For answer to = 34 d must be +(286+34)
So d= +320

2-28 = -26
78-89 = -11
-26 -11 = -37
-37 + d = 34
d = 71

2-28x78-89+d=34
28x78=2184
2-2184-89+d=34
2-2184=2182
-2182-89+d=34
-2182-89=-2271
-2271+d=34
add -2271 to both sides...
d=-2237
Atleast, that's what I got

csucdartgirl is correct. Using the order of operations, d does equal 2305. Please use that answer, all of the rest are wrong...
