How to pass integers to the "binom" function?

Questions
1

If I put a variable into $binom(#a,#b)$ it raises the error “expected content, foud interger”.

Follow the example:

#let triangle(n) = (
  for i in range(0,n)
    [#align(
      center,
      block[
        #for c in range(0,i +1) [
        #box(
            $binom(#i,#c)$
        )
        #h(1em)
        ]
      ]
    )
  ] 
)

if I put the variables inside the error disappear but the number is printed inside .

addeding “” before the first parameter the error disappear:

#let triangle1(n) = (
  for i in range(0,n)
    [#align(
      center,
      block[
        #for c in range(0,i +1) [
        #box(
            $binom(""#i,#c)$
        )
        #h(1em)
        ]
      ]
    )
  ] 
)

Wrap i and c with str to convert them strings.

Also, you can call math.binom to avoid extra $$.

#let triangle(n) = (
  for i in range(0, n) {
    align(
      center,
      block(for c in range(0, i + 1) {
        box(math.binom(str(i), str(c)))
        h(1em)
      }),
    )
  }
)

#triangle(5)
