    Code:
    X = A + B;
    X = A - B;
    X = A * B;
    X = A / B;
    Note that your "unknown" goes on the left hand side.
    The equal sign is the assignment operator. You are assigning the value on the right to the variable on the left.

    [EDIT -
    And, be careful when dividing integers 1 / 2 won't give the right answer, because the result will be a truncated integer. 1.0 / 2.0 will result in a floating point answer.

    Code:
    int number1 = 5;
    int number2 = 10;
    int number3;
    
    number3 = 1 + 1; // = 2
    number3 = number1 + number2; // = 5 + 10 = 15
    number3 = number2 / number1; // = 10 divided by ( / ) 5 = 2
    number3 = number2 - number1; // = 10 - 5 = 5
    number3 = number3 * 2; // = the previously stored number ( 5 ) x 2 = 10
    number3 = number3 + 5; // = the previously stored number ( 10 ) + 5 = 15;
    number3 += 5; // = the previously stored number ( 15 ) + 5 = 20 (  number3 += is just like saying number3 = number3 +
    The colored text is past the // symbols and therefor a comment, and not part of the code, just text to explain the line.
