Find the result of the following expression if, M denotes modulus operation, R denotes roundoff, T denotes truncation:
M (373,5) + R (3.4) + T (7.7) + R (5.8)
Explanation
 M denotes modulus operation, R denotes roundoff and T denotes truncation operation.
 M (373,5): Dividing 373 by 5, remainder will be 3.
 R (3.4): As 0.4 is less than 0.5, it will be rounded off to 3.
 T (7.7): Removing fractional part, 7.7 will be truncated to 7.
 R (5.8): As 0.8 is greater than 0.5, it will be rounded off to 6.
 Given expression will be reduced to
 So, value of the given expression will be 19.

Evaluate the expression M (843,11) + R (5.8) + T (7.7) – R (3.4) where M stands for modulo arithmetic, R stands for Roundoff operation and T stands for Truncation Operation.
Explanation
 M denotes modulus operation, R denotes roundoff and T denotes truncation operation.
 M (843,11): Dividing 843 by 11, remainder will be 7.
 R (5.8): As 0.8 is greater than 0.5, it will be rounded off to 6.
 T (7.7): Removing fractional part, 7.7 will be truncated to 7.
 R (3.4): As 0.4 is less than 0.5, it will be rounded off to 3.
 Given expression will be reduced to
 So, value of the given expression will be 17.
