Helix Oxford Scientific Calculator, 240 Functions, Two-Line Display, Protective Cover

Helix Oxford Scientific Calculator, 240 Functions

Helix Oxford is a scientific calculator with two-line display for Key Stage 3 and 4 students who need dependable maths support at a sensible price. It packs 240 functions, from everyday arithmetic to trigonometry and statistics, into a compact 15.5 x 8.4 cm body. A sliding hard cover protects it in a bag, and if one goes missing at school, replacing it will not sting the family budget.

Two Lines Catch Mistakes One Line Hides

Single-line budget calculators show only the final answer, so a mistyped number slips through unnoticed and costs marks. The Helix Oxford shows the calculation and the result together on a two-line, 10-digit display with a 2-digit exponent, letting students check their working before writing it down. Power comes from two LR44 button cells, included in the pack and easy to swap. With 240 functions and a protective sliding cover, it covers secondary school maths well, backed by a 12 month warranty from Helix.

Why Schools and Parents Pick It

• 240 Functions: Handles everyday arithmetic through to trigonometry and statistics for secondary school maths lessons and homework.
• Two-Line Display: See the full sum and the answer at once, making it easier to spot input errors.
• Sliding Hard Cover: Protects the keys and screen in a crowded pencil case or school bag.
• Replaceable Batteries: Two LR44 cells come included and can be swapped quickly when they eventually run down.

FAQs

Q: Is it durable enough for everyday school use?

A: Yes. It is built for daily use in a school bag, and the sliding hard cover protects the keys and display from knocks. The replaceable LR44 batteries mean it keeps going for years rather than being thrown away.

Q: Can students use it in exams?

A: It is designed for Key Stage 3 and 4 maths. Exam boards normally allow scientific calculators that do not graph or store programs, but always check your exam board's current rules before the day.

Q: When will my calculator arrive?

A: Orders are packed promptly and sent on fast-tracked UK transit with a dependable courier service, so it should reach you quickly and be ready for the next homework session or test.
