Detailed Solution

The given expression is [37−(−8)]+[11−(−30)] .
By the integers rule the operation between two negative sign is always positive.
So, 37– (– 8) =45 and 11– (30) = 41.
Considering the expression [37−(−8)]+[11−(−30)] , its simplification is as follows.
=[37−(−8)]+[11−(−30)] =45+41 =86 The result upon simplification is 86.
Thus, the correct option is 1.
