a= -1
b= 2
c= 3
d= -5

a+b-c+d


Sagot :

-1+2-3+(-5)= -7
-1+2 will be easier if it's like +2-1 or 2-1 = 1
While, -3 + (-5) will change the signs and be -3 - 5
The plus sign was chnanged into - and the negative sign of five was changed into positive....and the result was -8
When you combine 1 and -8....it will be 1-8 = -7

a + b + c + d

(-1) + (2) - (3) + (-5) = N
(-1) + (-5) - (3) + 2= N
- 9+ 2 = -7
   
The answer is - 7.
