Why am I learning this?

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?

"I think these are great! So useful and handy, the children love them.
Could we have some on angles too please?"

Go Maths

Learning 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 page is an alphabetical list of free activities designed for students in Secondary/High school.

"I am commenting to show you a wrong answer. Me, my teacher and my friends around me have been trying to solve this equation. We believe that you have your answer wrong and you may need to check it. The question is:
If you worked out the answer you would know that y=12. Unfortunately, when I submitted that answer, it was wrong. I hope you take this into consideration and I hope I will not find any more problems that I believe are wrong.
Your sincerely,
Henry J. Spencer."

"Thanks Henry for pointing out the error with Level 5 question 2. It has now been corrected. The questions that you see are drawn from a database containing a number of different versions of the question type. One of the versions is chosen each time the page is loaded. I hope you will not find any other errors but please let me know if you do. I am very grateful for the time you took to flag up the mistake. Thank you again."

Description of Levels



Level 1 - Simple equations where the solution can be found by performing one operation on both sides of the equation.

Example: \(8n = 64\)

Level 2 - Simple equations where the solution can be found in two steps.

Example: \(9e + 6 = 78\)

Level 3 - Equations where a multiple of the unknown and a constant are on both sides.

Example: \(4y - 7 = 3y - 4\)

Level 4 - Equations including brackets.

Example: \(2(4r + 7) - 9 = 21\)

Level 5 - More complex equations requiring multiple steps to find the solution.

Example: \(6(10h + 3) + 4 = 7h + 287\)

Solve to find Fractions - A four-level set of exercises in which all of the equations have solutions that are fractions.

Example: \( 5x+2=2x+4\)

Equations with Fractions - A five-level set of exercises taking your equation solving skills one step further.

Example: \( \frac{6x-4}{2}=13 \)

Old Equations - Solve these linear equations that appeared in a book called A Graduated Series of Exercises in Elementary Algebra by Rev George Farncomb Wright published in 1857.

Nevertheless - A two-player, equation-making game based on Level 2 type equations.

Exam Style questions are in the style of GCSE or IB/A-level exam paper questions and worked solutions are available for Transum subscribers.

Here is an example showing a good way to solve an equation of this type (Level 3) by thinking of the two sides of the equation as two sides of a balance. The equation will remain balanced only if you do the same thing (multiply, divide add or subtract) to both sides.

5x + 3 = 3x + 15
Subtract 3 from both sides
5x = 3x + 12
Subtract 3x from both sides
2x = 12
Divide both sides by 2
x = 6
