Hi everyone this is just a little post about inverse operations. I know some people still find things confusing. I found this website that shows different examples and ways of working with inverse operations. It also goes into some more complicated inverse operations such as square root and exponents and more. Check it out and after you read it if you want there are interactive questions at the bottom. http://mathsfirst.massey.ac.nz/Algebra/InvFun/InvOp.htm Just trying to help a bit! :D Jon
