2 minus 2/5 plus 1/2 minus 4 = -1.9
if the question u are asking is something like this 1/2 - ( - 1/2 ) then the answer is simple all you have to do is solve the equation like this 1/2 - ( - 1/2 ) = 1/2 + 1/2 = 2/2 = 1 its the - (-1/2) that is important remember the rule minus and minus equal plus plus and plus equal plus minus and plus equal minus remember and i hope it helps :)
1 minus 1/2 minus 1/3 is equal to 0.166667
1 - (-2) = 1 + 2 = 3

1/2
5 and 1/2
2 quarts
Five and a quarter minus two and a quarter is equal to 5 1/4 - 2 1/4 = 3.
5m + 7 - 2m - 1 = 3m + 6
9 - 11 - 2 - 2 2/3 + 6 1/3 = -1/3 or minus one third. Expressed as a decimal, this is equal to -0.3 recurring (that is, -0.3333...)
Five minus 2 does not equal to 4
11/12 − 1/2 = 5/12
suckers this is easy ha ha
