1, +-*/(arithmetic operator)

+ Number has two functions

When encountering numbers, just press the above + for example:

int i=2;

int j=3;

i + j is equal to 5

If a string is encountered, two strings are joined, for example:

String s= "abc";

String s2= "EFG";

The result of S + s2 is "ABCEFG"

3. Type conversion

int j = Int. Parse (t1. Text);//int. Parse (String) transforms a string into an orthopedic
int i =int. Parse (T2. Text);

int c = i + j;//two X-shaped addition

T3. Text = C.tostring ();//Call the ToString () method to convert the shaping to a string
