In winform The value of a label is in "label2.text" This is a string, to convert the string to a number use Convert.ToInt32(label2.text); Because a division can create a floating point number, use the float-type for the variable number4. Represent number4 in a label use number4.ToString(); https://code.sololearn.com/cgD3H4h5wR5t

Make a property in the custom control. Then you can use customcontrol.label2value in your code. This is the code in the customcontrol. private int _label2value public int label2value { get { return _label2value;} set { _label2value = value;} } Make sure that when label2 is changed you set the value of _label2value. https://www.dotnetperls.com/property https://www.c-sharpcorner.com/article/understanding-properties-in-C-Sharp/ https://www.w3schools.com/cs/cs_properties.asp Keep coding, keep asking. You are doing well.
