Arithmetic Operators; Assignment and Comparison; Operator Precedence; Unary Operators

So I am coming to the end of the recap of my 'Swift Basics' course. Once I've finished that, I should feel pretty secure with the essentials. The next task after this will be to go over the other courses I have completed. Realistically, by this time next week, I should be ready to continue with learning 'new' information! Arithmetic Operators There is some technical mathematical information about operands. We now move on to the four main operations - add, subtract, multiply and divide. The other function that can be used is the remainder operator (% is used). E.g. 9 % 4 would give 1. let height = 12 let width = 10 let area = height * width Simple stuff for using multiplication, in this case.  The next part is dividing the area by 10.764, to have the answer in metres. However, this is a double. The most logical thing to do is changing height to 12.0 and width to 10.0. Or, you can declare height and width as doubles, using the syntax of the ...
