         First I want to thank you for this forum.And sir I have my calculator program code here and I runned this program succeeded.But only the numbers, addition,subtraction,point,clear screen and equal codes are running.
    

    And without the multiplication and division code are not in running. And if I click any number and I click the multiply or divide it in any numbers and I click the equal button are only zero is showed it in the textbox. And now sir I want you to check my multiplication and division code there below in the btnMultiplyClick and below in the btnDivisionClick is correct and after that I think this two math operators will be run if they have a correct if else code below in btnEquals_Click,and that also I don`t know how to modify it to be correct and also get into run??
