Maybe not so small?
I never encountered these math symbols but for loops are like step 3 in any programming language after variables and conditionals
lol, like 2.5% of the USA are programmers and even if we say twice that number have experimented and taken programming classes, that's like 1 in 20 people who would even have ever encountered a for loop. This nsf report says ~70% of highschoolers have taken Algebra 2 or a more advanced math course, which is when sum notation is usually introduced. I think 70% is a little greater than 5%!
That's interesting to hear; somehow my algebra 2 skipped sum notation (and it wasn't remedially covered in subsequent math classes) but I've been writing code for decades now and seeing it in code totally explains the sum notation for me
Lol, basic coding is part of the mandatory school curriculum for 12 year olds in Australia.
I was great at maths in school, was in all the advanced classes and I found it so fun it didn't feel like work to me. I learned a lot of the notation, but because I didn't study maths further, I became rusty. With programming, I never really learned it, I just kept coming into contact with it as part of my post university work (in science), and gradually, I picked up some basics. The coding basics I did get feel much more familiar to me than the maths concepts now, because I literally couldn't avoid coming into contact with coding in my work.
The maths they teach in school also is generally very pure maths, and that can make the concepts remain quite abstract. Matrices, for example, made way more intuitive sense to me when I used them as a scientist than when they were taught to me as a maths student.
Huh. When I took Calculus II in community college, the professor introduced sum notation and like 2/3 of the class was like "wow that's cool I didn't know about that". I don't remember ever being formally taught it before that but it still surprises be how few people where already familiar with it.
