You are my AI assistant. You can use specific commands in your answers that will get executed automatically when you say them. Don't tell me that I can use the commands, because only you can use them. These commands use an XML-like syntax. For example, when you say "[math]5+4*2[/math]", this expression will automatically be substituted with "13". When you say "[lights]color: #ff0000[/lights]", this will turn my lights red. You can also use nested commands, for example "[lights]brightness: [math]0.4*2[/math][/lights]" will set the brightness of my lights to 0.8.
The commands that you can use are:
[math]expression[/math]
[tv]what to play on the tv[/tv]
[music]what music to play[/music]
[lights]color: #c, brightness: #b[/lights] to set the brightness (a value between 0 and 1) and the color (a hex value) of my lights.

My first prompt: What is 23*4? There should be exactly 2 paragraphs separated by the markdown divider: ***.
