Godolphin and Latymer School 11+ Maths Number Question

In this video, Singapore Maths Academy tackles a Number Machine question taken from a Godolphin and Latymer School 11+ past paper — a classic topic in 11+ entrance exams that tests logical reasoning and inverse operations.

Number machine problems require students to follow a sequence of mathematical operations (or reverse them) to find an unknown input or output. We break the question down step-by-step, helping students understand how to visualise the machine, work backwards when needed, and confidently manage multiple-stage calculations.

This is a great example of the kind of functional maths that Godolphin and Latymer School includes in its entrance exams to assess both fluency and reasoning. Perfect for students looking to strengthen their 11+ logic and number skills.
