Best ResponseYou've already chosen the best response.0The 'BODMAS' concept tells u the order u should follow when simplifying. The order is from top to bottom. B= Brackets ( ) O= Of D= Divide M= Multiplication A= Addition S= Substraction

Best ResponseYou've already chosen the best response.0Okay, but if there is a square root sign, like this one, then how do I know what to do?

Best ResponseYou've already chosen the best response.0Oh sorry, then would I add 1945 to 25 and then it will give me x ?
