Answer:
Ascending order= (A - E), (A - D), (C - D), (D - E), (C - B)
Step-by-step explanation:
Basics to keep in mind: If the greatest number of an addition or subtraction is negative, then the answer carries negative symbol.
But if the Greatest number is positive, then the sum or difference carries the positive symbol.
Note that - + - is equal to plus and the sum as said carries the symbol of the greatest value.
Answer: Since AD is taken positive and BC negative,
A (BC) becomes -2650
B (BC) becomes -432
C (AD) becomes 204
D (AD) becomes 1161
E (AD) becomes 1470
Now,
(A - D) = -2650 -(+1161) = -2650 - 1161= -3811
(C - B) = +204 - 432 = -228
(D - E) = 1161 - 1470 = -309
(C - D) =204 - ( +1161) = -957
(A - E) = -2650 - ( +1470) = -4120
Let's arrange these integers to get their ascending order
( -4120), ( -3811), ( -957). ( -309), ( -228) i.e.
(A - E), (A - D), (C - D), (D - E), (C - B).
