Thanks for all the replies , I have few more dumb questions ... I have learned this much myself , i wish there was one book that explains it all , but i cant find that one book that explains everything like this , [img]https://i.ibb.co/YTz3cFv/Untitled.png[/img] I know by now that we need to find lcm for fractions , But where do we use the gcf for ?
Can someone tell me some good books or websites where i can learn basic mathematics ? I don't like video tutorial sites like khan academy . anything else other than that is cool . For example , any pdf that teaches operations of signed numbers ? Thanks
