Then we are solving 0. Multiplying both sides by 4 or dividing both sides by 0. We can also see that 0. One combination is questions 1, 3, 5 and 7. We could try to list them all out or use the Counting Principle. We know there are four pairs of questions, she answered four questions correctly, and she answered one question correctly in each pair of questions. That means that in the first pair of questions, there are two options.

She either got 1 or 2 correct. When considering the second pair of questions, she either got 3 or 4 correct, and what she did on the first pair has no bearing on the second pair.

Now the third pair of questions has 2 options, again neither of which is dependent on what happened with the first two pairs of questions. You can see that we can take the four combinations listed previously, and add 5 to each of them and then add 6 to each of them, thus doubling the number of combinations.

Finally, we have our fourth pair of questions, which gives us another two options. Skip to main content.

Students have 40 minutes to complete the Sprint Round. This round is very fast-paced and requires speed and accuracy as well. The earlier problems are usually the easiest problems in the competition, and the later problems can be as hard as some of the Team Round questions.

No calculators are allowed during this round. Students have 6 minutes to complete each set of two problems. Students may not go back to previous rounds or forwards to future rounds even if they finish before time is called.

Calculators are allowed for the Target Round. Usually comprised of one "confidence booster" and one hard problem.

These problems typically include some of the most difficult problems of the competition. Use of a calculator is allowed and required for some questions. High scoring individuals compete head-to-head until a champion is crowned. People compete from off a screen taking 45 seconds or less to finish the problem. The Countdown round is run differently in various different chapter, state, and national competitions.

In the national competitions, it is the round that determines the champion. Calculators are not allowed, but scratch paper will be provided.

In the chapter and state competitions, the countdown round is not mandatory. However, if it is deemed official by the chapter or state, the following format must be used:. This process is continued until the countdown round reaches the top four written competitors.

Starting then, the first person to get three questions correct wins as opposed to the best-out-of-three rule. If the countdown round is unofficial, any format may be used. Single-elimination bracket-style tournaments are common. At the national competition, there are some structural changes to the countdown round.

The top 12 not the top 10 written finishers make it to the countdown round, and the format is changed from a ladder competition to a single elimination tournament where the top four written competitors get a bye.

This setup makes it far more likely for a 12th place finisher to become champion, and it makes it less likely for a first place written finisher to become champion, equalizing the field. But even then, a 12th place written competitor will have less of a chance to become champion than the top 4, because the top 4 get a bye.

Until the semi-finals, the scoring is best out of five advances.

Sprint Round - This is a minute multiple choice round consisting of thirty questions. Students may not use calculators on this round. Target Round - Four pairs of problems are administered, and students have 6 minutes to complete each pair.

Students may use any calculator allowed for use on the SAT. Team Round - One to four team members work together for 20 minutes to answer ten questions. Answers must be fully simplified and, where appropriate, given in the format asked for in the question. Units of measurement are not required and will be disregarded during grading if given.

For instance, if the correct answer is 42 inches, then "42", "42 inches", and "42 pigeons" will all be marked correct, but "3. Ties are broken by comparing students' sprint scores, then by comparing target scores weighted by item analysis.

For purposes of awards, a school's overall score the "sweepstakes" score is obtained by adding the top 4 individual point totals from the school, dividing by 4, and adding the school's top score on the team round. A maximum team total would be points points if the school had four members with perfect individual scores, for the team test. Ties are broken by comparing team test scores weighted by item analysis.

The following tests are offered at the elementary school contests mathleague.Then, when I was 15, a new station was launched with imaginative name of Channel 4. The first program to air on this new channel was a game show called Countdown. Countdown is still shown today and is one of the longest running game shows in the World. At the time of writing this article, over 5, episodes have been broadcast.

The show was not entirely original in concept, being based on a slightly earlier game shown in France called Des chiffres et des lettres Numbers and Letters. The Countdown game tests contestants' numeracy and word-making skills.

The tiles are arranged into two groups: Large Numbers and Small Numbers. One contestant selects as many numbers as desired unseen from the large set between none and all fourand the balance are pulled from the small set to make six numbers in total. At no intermediate step in the process can the current running total become negative or involve a fraction.

Some say that only numbers range are generated which are the rules in the French variantand other say that any three digit numbers is possible.

Also, there can only be one each of the larger numbers. Here's an example of the game in action. In this instance, one number was selected from the large set, and the rest from the small set.

There are multiple ways to solve this. The smallest solution requires just four numbers:. For 26 years, this host role was performed by the talented Carol Vorderman. Are all problems solvable for a perfect score? Does there exist a three digit number that is not achievable by any combination of digits?

If not, what is the hardest number to achieve? This was a fun piece of code to write. I elected to use a brute-force approach. There are 13, distinct ways of picking the numbers following the rules. Then, for each of these distinct subsets, the number of distinct ways these numbers can be arranged in order was determined.

The most obvious way to process these was to use Reverse Polish Notation to store the calculation postfix as opposed to the more traditional infix. A trap that needs to be avoided is the ordering the operators should be applied. In RPN notation these distinctions are obvious See table. Calculating all possible solutions is easy using RPN by permuting the order operators and operands within the constraints of a stack, so some combination as not possible; you can't operate on numbers if there are none in the stack!

An added benefit of using RPN is that, at the end of any operation you can check the stack and that will give you a possible intermediate solution remember not all numbers need to be used for a valid solution. This is not a valid answer, as it is less than a hundred the lowest possible target.

However the next operation is multiplication by 5. This gives a result ofwhich is valid. There are some obvious optimisations that can be made in the algorithm plus a couple of things to watch out for :.


There is no benefit in multiply by 1 at any stage. This just makes a longer solution. If at any time the intermediate solution becomes negative, we can instantly bail on that solution. You need to make sure you catch any potential divide by zero calculation that might happen as you test for possible solutions.Since we want members to make the most out of their stay on this wiki, we need rules.
