Hello. I want to be able to create any mathematical equation or expression. So, one thing I want to confirm is that, to create any complex equation or expression, I should make use of Order of Operation - PEDMAS or BODMAS. Correct? The Order of Operation governs the result, and the Order of Operation is the way by which any complex equation or expression is created. For example: y = 4x2 + √16 + (x + 2) The above equation is built by having BODMAS or PEDMAS in mind, because when I try to get the value of 'y' at a value of 'x' (when plotting graph), I could follow the Order of Operation to arrive at a result, i.e, by a well-defined rule - like BODMAS or PEDMAS. Correct? Thanks.
