Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$\var{a}! =$ Unnamed gap

Advice

$n!$ is the product of the numbers $1, \dots, n$ . You can work that out by hand, or most calculators have a factorial function, normally labelled n!.

a)

$\var{a}! = \var{show_factorial(a)} = \var{fact(a)}$

b)

$\var{b}! = \var{show_factorial(b)} = \var{fact(b)}$

c)

$\var{c}! = \var{show_factorial(c)} = \var{fact(c)}$

Give a worked solution to the whole question.
