Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 1 May 'Starter of the Day' page by Phil Anthony, Head of Maths, Stourport High School: "What a brilliant website. We have just started to use the 'starter-of-the-day' in our yr9 lessons to try them out before we change from a high school to a secondary school in September. This is one of the best resources on-line we have found. The kids and staff love it. Well done an thank you very much for making my maths lessons more interesting and fun." Comment recorded on the 8 May 'Starter of the Day' page by Mr Smith, West Sussex, UK: "I am an NQT and have only just discovered this website. I nearly wet my pants with joy. |
Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month. The newsletter is then duplicated as a podcast which is available on the major delivery networks. You can listen to the podcast while you are commuting, exercising or relaxing. Transum breaking news is available on Twitter @Transum and if that's not enough there is also a Transum Facebook page. |

Go MathsLearning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths main page links to more activities designed for students in upper Secondary/High school. | ||

Sum of the Signs - A much easier puzzle if you are finding Unbeknownst too difficult.
Level 1 - 3 unknowns. Solution could start with 2 simultaneous equations
Level 2 - 4 unknowns. Solution could start with 2 simultaneous equations
Level 3 - 4 unknowns. Solution could start with 3 simultaneous equations
Level 4 - 4 unknowns. Solution could start with 4 simultaneous equations
Level 5 - 5 unknowns. Solution could start with 4 simultaneous equations
Simultaneous Equations - You can practice solving simultaneous equations with this set of exercises.
More Puzzles - For more challenges and the opportunity to collect more trophies.
Answers to this exercise are available lower down this page when you are logged in to your Transum account. If you don’t yet have a Transum subscription one can be very quickly set up if you are a teacher, tutor or parent.
See the National Curriculum page for links to related online activities and resources.
You will need pen or pencil and paper to do some working out.
The puzzles can be solved using algebra. Here is an example:
Let s represent the value of the star.
Let b represent the value of the ball.
Let f represent the value of the flower.
From the bottom row f + 2s = 16
From the centre column 2f + s = 17
You now have two simultaneous equations. Double the first equation to give a third:
2f + 4s = 32
Subtract the second equation from the third:
3s = 15
Divide both sides of this equation by 3.
s = 5
So the value of the star is 5 and this can be sudstituted in the first equation.
f + 2 × 5 = 16
f + 10 = 16
f = 6
So the value of the flower is 6
These two values can be substituted into an equation obtained from the first row to find that the value of the ball is 7.
