Translate the following phrase to a mathematical expression.

the product of a number and nine

n + 9
n - 9
9n
n/9

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

this is not the answer this is just a question. is this middle school math?
