Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

The score is $100$ for one guess, with $10$ less for each extra guess, and never below $0$ . What is the score for $1$ , $3$ , $7$ and $12$ guesses?

Need a reminder? The key ideaShow

max(0, value) keeps a value from going below zero.

The worked solution

Have you tried it?

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, compare your working with the solution.

Formula. $\text{score} = \max(0,\ 100 - 10 \times (\text{tries} - 1))$ .

Guesses	$100 - 10 \times (\text{tries} - 1)$	Score
1	$100$	$100$
3	$100 - 20$	$80$
7	$100 - 60$	$40$
12	$100 - 110 = -10$ , so $0$	$0$

max(0, ...) stops the score from going below zero.
