When typing calculations from the keyboard, mathematical operators that require use of the SHIFT on the main keyboard do not work

For example multiplication and addition --->  *=SHIFT+8, +=SHIFT+= do not work.
Similarly, the operators ),  (,  ^,  are not possible with keyboard input.

Reproducible: Always

Steps to Reproduce:
1. Open kcalc
2. e.g.  type 7*5=
3.

Actual Results:  
Answer: 75   (since * is not recognised through SHIFT+8)

Expected Results:  
Answer should be: 35

Using mouse to click buttons works.
Using the numerical keypad works (but *, /, +, - do not require SHIFT key on keypad and other operators are still not possible from the keyboard such as (, ), ^
