Answer 2

In Case of Addition and Substraction !

Answer:

IF X = A ± B

then ▼X = ▼A ± ▼B

Note :- "▼" putted as delta to denote and it's not correct sign..

i.e,. for both addition and Substraction the absolute errors are added up. The percentage of error in the value of X is Percentage error in value of

X = (▼A ± ▼B/ A ± B )× 100.
