What Is the Overhead Calculator Used For?
An overhead calculator sits on an overhead projector so that its keys and display are projected onto the screen, which this model’s transparent keypad and display allow. Because it is a true fraction calculator, the projected display shows fractions as numerator over denominator, the way they are written in an exercise book. In primary and middle-school maths a teacher can then show how fractions are added, simplified, changed between mixed and improper form or into decimals, and how a division leaves a remainder.
What to Specify When Ordering
- Quantity — for example one for each classroom that uses an overhead projector.
- Student calculators — the Fraction Calculator or the See N Solve Fraction Calculator can be quoted on the same enquiry.
Frequently Asked Questions
What does “true fraction calculator” mean?
It displays and calculates fractions as numerator over denominator rather than only as decimals.
Which conversions can it make?
Between mixed and improper fractions and between decimals and fractions, each at the touch of a key. It also simplifies fractions and divides with a remainder.
Why are the keypad and display transparent?
So that light from an overhead projector passes through them and the keys and display appear on the screen for the whole class.
What details are needed for an export quotation?
The quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling requirements, and the tender reference if applicable.
Who manufactures the Overhead Calculator?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of educational and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The Overhead Calculator is made at JLab’s own works rather than bought from a trader, so schools, dealers and importers deal with the manufacturer directly. JLab exports worldwide and ships to buyers in every region — for example the USA in North America, Tajikistan in Central Asia, Morocco in North Africa, El Salvador in Central America and the Caribbean, and Belgium in Western Europe.
