It is: -4+5 = 1
-3+-1 = -4
- 4 + (- 4) = - 8
0, of course! 4+-4=4-4. One negative plus one positive equals one negative.
Z= -1
-4 + -5 + -2 + -1 = -12 (negative 12).
-8
-4+0-(-4)+(-4)-1= -4+0+4-4-1= -5
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
It is: -4+5 = 1
-3+-1 = -4
The total sum is -12 or negative twelve.

-3 + -2 + 4 = -1
