How to calculate a variable that contains digits

[vsub]

If I set the number into a variable or a message box,then AHk calculates them but if I copy the numbers and use the clipboard as variable,AHk will display them rather than calculate them

Var = 5+5
Msgbox,% var ; displays 5+5

var := 5+5
msgbox,% var ; displays 10

var := Clipboard ; the clipboard contains 5+5
msgbox,% var ; displays 5+5

Var1 = 5+5
var2 := var1
msgbox,% var2 ; displays 5+5

Yes I know that but why AHK can calculate variable with digits with no extra functions but need that code if the calculation is in a variable

Can calculate
Msgbox,% 5+5

Can't calculate and need that extra code to do the calculation
var = 5+5
msgbox,% var
