Use interval notation to describe the graph. What is the resulting interval?
Write three linear inequalities that are equivalent to
Function to grab specific digits from a number?
Recently I’ve been thinking a lot about grabbing digits from numbers, for things like calculating multiplication persistence, i.e. turning into a . I’ve been able to come up with
to output the number of digits of the given number x, as well as
which outputs the first n digits of any number x. But that’s about as far as I’ve been able to think up. Is there any way to construct a function that retrieves the nth digit of a given number? Forgive me if my notation or comprehension is poor, I have no formal education in this field of maths.
