11+ Maths Skills: Algebra
140 questions on Algebra alone, with every wrong option traced to the exact mistake behind it, so you fix the cause, not the symptom.
- 140questions
- 6timed tests
- 120minutes of practice
Try three real questions on this topic.
One from each difficulty band. Pick an answer, then press submit to see it marked and explained.
What is the expression 5a + 3b − 2a + 4b when it is simplified?
When a = 5 and b = 3, what is the value of a² − 2b?
Two numbers add up to 34. Three times the smaller number equals the larger number plus 6. What is the smaller number?
That is 3 of the 140 questions. Every one of the rest is marked the same way, with the worked solution and the mistake behind each wrong answer.

Try a free timed maths test first.
Twenty questions in twenty minutes, in the GL format, marked the moment your child finishes, with a breakdown of which topics need work. No sign-up.
Is this right for your child?
Buy it if
- Your child keeps dropping marks on Algebra specifically
- They have met the topic in class and need it to become automatic
- You want 140 questions on one topic, not three buried in a mixed paper
Skip it if
- They have never been taught Algebra, this tests, it does not teach
- You want broad coverage before the exam, a mixed Maths Pack fits better

This is what every wrong answer gets
Three real questions from the pack, with the explanation exactly as it appears in the mark scheme, one Bronze, one Silver, one Gold.
A number n satisfies the equation n + 17 = 45. What is the value of n?
The inverse of adding is subtracting; checking 28 + 17 = 45 confirms the answer.
Leah thinks of a number, multiplies it by 4 and then subtracts 6, and her answer is 30. She also has 12 stickers in her pocket. What number did Leah think of?
The stickers are a red herring; nothing in the question connects them to the calculation.
Five consecutive whole numbers add up to 190. What is the sum of the smallest and the largest of these numbers?
The smallest and largest are equally spaced either side of the middle, so their sum is twice the middle number.
Drill the topic until it stops costing marks.
140 questions across 6 timed tests, each with a worked solution. Yours permanently, no subscription.
We check the answers before you have to.
Most 11+ material asks you to take the answer key on trust. Ours is machine-checked and the check is tied to the questions by a content hash, edit a question and the build refuses to produce the pack until it has been verified again. That is a gate in the build, not a promise on a sales page.

FAQs
Which exam is this for?
11+ maths for GL, CEM-style, CSSE, SET, FSCE, Quest and independent entrance. The 11+ maths syllabus is national, Algebra is on the syllabus for all of them. What differs is format. Every question here is five-option multiple choice against the clock, which mirrors GL and CEM-style papers directly. If your child sits a written-answer paper such as CSSE in Essex or an independent school's own, use these to build topic fluency and speed, then rehearse setting out working on that school's past papers.
Is this one topic only?
Yes, deliberately. All 140 questions are Algebra, spread across 10 sub-topics, so a weak area gets drilled properly rather than meeting three questions on it in a mixed paper.
Do I need to install anything?
No. It's a link that opens in the browser on a laptop, tablet or school Chromebook. The PDF is a normal download.
How long do I have access?
Permanently. It's a one-off purchase, not a subscription, and the PDF is yours to keep and reprint.
