45+92-56*2 = 45+92-112 = 25
45 * 2 = 90
5 + (2 x 7) - (18/5) = 15.4

Answer = 2 - (-3) = 2 + 3 = 5 minus minus means plus.
I work it out like this: (-2/15) - (-1/9) = (-2/15) + (1/9) ) [minus negative is the same as plus] = (-6/45)+(5/45) [change both to 45th as that is the lowest common multiple of 15 and 9] =-1/45 or negative1/45
0.5 x -2 = -1
2 minus 2/5 plus 1/2 minus 4 = -1.9
