.* and * give me different answer

F = [1.5 0.2; 0.2 1.3];
I = eye(2);

E = 1/2*(F'*F-I);

E =

0.6450 0.2800

0.2800 0.3650

E = 1/2*(F'.*F-I);

E =

0.6250 0.0200

0.0200 0.3450

Why did * operates differ from .*? Can someone show the math behind the .* operator? When I was doing it by hand I got the answer same as * operator.
