12 - 3 + (4 x 2) = 17
It is plus 4
x2_12x-3 = 0 Using the formula for solving quadratics: x = 12 plus/minus sqrt (144 - (4 x 1 x -3))/2 x = 12 plus/minus (sqrt 156)/2 x = 12 + (sqrt 156)/2 = 12.25 or x = 12 - (sqrt 156)/2 = -0.25
Positive 3 plus negative 5 minus negative 2 minus positive 4 is equal to -4.
-2 times -2 = plus 4 since minus times minus is plus
12 - 3 + (4 x 2) = 17
-4 + 12 = 8
12
-5 + (-4) - 12 - 20 - (-10) + 6 = -25
8 plus 4 minus 12 divided by 1 is 0.
18 + 12 + 0 - 4 - 10 = 16
It is plus 4
2 minus 2/5 plus 1/2 minus 4 = -1.9
4
it doesn't

13 - 4 + 12 = 21
