It is: -1--1 = 0
(-2 + 3i) + (-1 - 2i) = -2 + 3i - 1 - 2i = -2 - 1 + 3i - 2i = -3 + i
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

A negative minus a positive is a negative. i.e -1-(+1)= -2
Three times negative one equals negative three. In mathematical terms, ( 3 \times (-1) = -3 ). This is because multiplying a positive number by a negative number results in a negative product.

-3 - (-1)= -3 + 1= -2-2
negative 9 divided by negative 3 is 3 andnegative 3 minus 1 is negative 2
500-negative1 = 499
(-5)-(-3)-(-1)-1-3-5 (-2)-(-1)-1-3-5(-1)-1-3-5 (-2)-3-5 (-5)-5 (-10)
-3 minus -2 is -1.
The answer to negative 312 minus 34 is negative 346.
