Q: How do I try a free SEA Mathematics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live SEA CSEC Mathematics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for SEA Mathematics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Mathematics questions aligned to the SEA CSEC syllabus?

Every question is written against the published SEA CSEC Mathematics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real SEA past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Midday temperatures were recorded for five days: 28, 30, 29, 31 and 27 degrees Celsius. What is the difference between the highest and the lowest temperature?

Accepted Answer

4 — Award 1 mark. The highest is 31 and the lowest is 27, so the difference is 31 − 27 = 4 degrees. Answering 58 adds the two readings instead of subtracting them.
