What does everyone else think? Is it important to understand objects like expr etc?

]]>Yes it does.

My math isn’t great either, even though I took math in high-school, but I’ve found digging into math issues in Max development context a great way to refresh or expand my skills. Especially in my late high school years I lost attention for it but I’ve now been encountering lots of the stuff I skipped on back then and find them easy to pick up just because now they’re linked to practical issues, which I was totally missing in theory classes. The internet is full of resources to dig into. I usually need that math in openGL context.

]]>have you, for example, looked at the helpfile for % ?

it is pretty easy to understand what it does, and one does not need to know the way it is tought in

school or university.

i find it far more difficult to use +,-,+,/ to calculate the modulo or the div than using the % object!

expressions also also very useful. try start using it for +-*/ at first. it makes patches smaller

and eventually more CPU friendly.

can you say [expr $f1+$f2-$f3] ?

]]>I am very much in the same position and have found that, over the last 5 or 6 years of Maxing, that my maths knowledge has increased, just by using objects such as [expr], [curve~], [sin~] etc. Patching logic is a great teacher too, as is this forum. So, maths skills are not the sine qua non of patching – they certainly help though, and I do envy those patchers/contributors with a clearer grasp of geometry and algebra.

Like a visitor to a foreign country, you can learn the language first, or (as I do) struggle initially and then learn more the longer you stay!

]]>And as always, see Peter Elsea’s invaluable Max Tutorials, where you’ll find a cheerful little piece called “Befriending Math” – the last page is particularly useful.

I keep going back to my school books trying to pick up where I left off 30-something years ago, in the hope that I’ll one day be able to get more out of books like Dave Benson’s ‘Music – A Mathematical Offering’ http://homepages.abdn.ac.uk/mth192/pages/html/maths-music.html

Pay more attention at school, kids – one day your brain will be mush and it will interfere with your Maxing…

Looks like a read of that Befriending Math paper is a good idea. The math anxiety scenario seems applicable to my past experience!

]]>With integers:

7 / 3 => 2

7 % 3 => 1 (“one left over after dividing by three”)

I have never understood what people find hard about that, but apparently a lot of people do. And it’s dead useful.

]]>i think [expr] syntax is sometimes scary even if you understand math implied : [expr pow($f1,2)] is not really intuitive ;-)
