Let me explain, from the name itself we can derive what it is i.e. "COMPUT+ER", now compute means to calculate and a Computer is just a computing or calculating device and nothing more.
Now what kind of calculation? only the very basic ones that we learn in at our primary school i.e.

A MATHEMATICAL APPROACH TO DEFINING COMPUTERS:-
A computer or a computing System can be defined as an information processing system whose function is to map a set A of input information items(i.e. a PROGRAM and its DATA) into an output set B(the result computed by the program acting on the data). Example:-

f(a,b) = c
where a, b:- are discrete data
f:- program or the instruction
c:- output
