 Now remember the associative law, we can associate certain parts of an expression For that to be executed first the same happens in computer languages like Julia And I've just shown you here the order of operations now These are all little symbols that you'll be unfamiliar with some of them. We would be there's our fraction and At least there's the little carrot sign there for What to do with powers if I double-click on that you can see how that was constructed What we're interested in is just a say say for instance we say 2 minus 4 Times 3 of course, it's going to do 4 times 3 multiplication comes before Subtraction so that's going to be 12 and so that's 2 Minus 12 and indeed we get our answer the negative 10 But we can force the issue by just simply putting our little parentheses around what we want to execute it first Times 3 so 2 minus 4 is negative 2 times 3 is going to be negative 6 So just forcing the associative law just associating things so that we can force the order in which these operations are executed so similar to normal pen and paper mathematics
