How do I insert a newline within a long formula using OpenOffice.org Math?

Found the answer om the OpenOffice.org forum. Rather than inserting newline, {}newline{} should be used instead.

In my case:

(x^6+x^4+x^2+x+1)(x^7+x+1){}newline{}
= x^13+x^11+x^9+x^8+x^7+{}newline{}
x^7+x^5+x^3+x^3+x^2+x+{}newline{}
x^6+x^4+x^2+x+1{}newline{}
= x^13+x^11+x^9+x^8+2x^7+x^6+x^5+x^4+x^3+2x^2+2x+1

To get it nicely aligned to the left, I used:

alignl (x^6+x^4+x^2+x+1)(x^7+x+1){}newline
alignl {}= x^13+x^11+x^9+x^8+x^7+{}newline
alignl {}""phantom{=}x^7+x^5+x^3+x^3+x^2+x+{}newline
alignl {}""phantom{=}x^6+x^4+x^2+x+1{}newline
alignl {}= x^13+x^11+x^9+x^8+2x^7+x^6+x^5+x^4+x^3+2x^2+2x+1

alignl causes the text to be aligned to the left; ""phantom{=} inserts an hidden =, which adds the extra whitespace before the line. (found at FAQ: How do I align my equations at the equality sign)

If you're curious how the formula looks like:
