Answer:
a) 9+(-3) + (-2) = 9 -5 = 4> 0 ⇒ Positive Sum
b) -12 +1 +11 = -12 +12 5 = 0 ⇒ Zero Sum
c) -3 +8 + (-4) = -7 + 8 -5 =-1 < 0 ⇒ Negative Sum
d) -4+9+(-10) = 9 -14 = -5 < 0 ⇒ Negative Sum
e) 3+(-2) + (-4) = 3 -6= -3 < 0 ⇒ Negative Sum
f) 2 + (-4) + 2 = 4 -4 = 0 ⇒ Zero Sum
Step-by-step explanation:
Positive Sum is defined as the condition in which the Sum of total of gains and losses is GREATER THAN ZERO.
Zero Sum is defined as the condition in which the Sum of total of gains and losses is EQUAL TO ZERO.
Negative Sum is defined as the condition in which the Sum of total of gains and losses is LESS THAN ZERO.
Now, here
a) 9+(-3) + (-2) = 9 -5 = 4> 0 ⇒ Positive Sum
b) -12 +1 +11 = -12 +12 5 = 0 ⇒ Zero Sum
c) -3 +8 + (-4) = -7 + 8 -5 =-1 < 0 ⇒ Negative Sum
d) -4+9+(-10) = 9 -14 = -5 < 0 ⇒ Negative Sum
e) 3+(-2) + (-4) = 3 -6= -3 < 0 ⇒ Negative Sum
f) 2 + (-4) + 2 = 4 -4 = 0 ⇒ Zero Sum
