Dear Nilesh
U do one thing. Type a number in the text box, use one variable, say number1. When u click command '+' the number in textbox must be stored in number1 and textbox is cleared. Now type another number. When u press command button '=' make

Number1 = Number1 + val(Text1.Text)
Text1.Text= Number1

Now the sum of both the numbers appears in the textbox.

If any other problem do ask. If solved kindly acknowledge.
