1 plus negative 10 is equal to -9.

Not necessarily. 5 + (-6) = -1, a negative 5 + (-5) = 0 or 5 + (-4) = 1, a positive.
4 + (-5) = -1
a negative number plus a negative number is negative. here is a proof.(-x)+(-x)(-1)x+(-1)x-1(x+x)-1(2x)-2xa negative number times a negative number is positive though.

negative -1/2+-1/2 = -1
Not necessarily. 5 + (-6) = -1, a negative 5 + (-5) = 0 or 5 + (-4) = 1, a positive.
Negative plus a negative is a negative. Ex. -1+-1=-2 Negative times a negative is a positive. -2*-2=4 But a negative [minus] plus a positive [plus] can be minus, zero or plus: For example, -3 + 2 = -1 -3 + 3 = 0 -3 + 4 = +1
some times 3+(-2) = 1 but 2+(-3) = -1
4 + (-5) = -1
a negative number plus a negative number is negative. here is a proof.(-x)+(-x)(-1)x+(-1)x-1(x+x)-1(2x)-2xa negative number times a negative number is positive though.
Negative. Adding a negative is the same as subtracting a positive. -2 + -3= -2 - 3= -5, not 1
6 + - 1 = 5 Here is a little table to help with manipulating double signs. = + = - = - = + NB If no sign is given then read it as (+). So for the above sum we could write + 6 + - 5 = +5
Negative plus Negative would equal positive in Maths. like this: -7 + -8 = 1 Because you're adding a minus It Will Not Equal a Positive it will Equal a Negative. -7+-8= -15. Because you are adding a negative to another negative. If the problem was -7+8= 1. Because you are taking seven out of that eight. If It were to be multiplication than a negative TIMES a negative would have been a positive(-8 x -7=56). And a negative TIMES a positive would be a negative (-8 x 7=-56).
