You really should go through the lessons in the Matlab Onramp tutorial if you don't understand how to do these very basic things.
Also, you are much more likely to get help if you show that you actually tried to solve the problem instead of assigning your homework to the Answers community.

a = 12; b = 34; c = .56;
a) (a + b)/c
Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

Error in connector.internal.fevalMatlab

Error in connector.internal.fevalJSON
In MATLAB, the only times that it is valid to have a non-matching bracket or brace, is inside a comment or a character string. Therefore the
a)
part of the required expression is invalid.
