You've written it wrong the first time, don't use implied multiplication.

You should read the manual / quick ref. guide for basic things like this, you'll learn a lot.

Just for reference, (in case you were wondering), the nspire doesn't like to multiply "x(1+y)" because it thinks that x is a function and 1+y is the argument.

Now I understand it.
Thank you.
