is a WriteView calculator?
A WriteView calculator is a scientific
calculator that can display fractions and symbols (such
that are used in mathematical formulas, as in the display
example shown here.
is a scientific calculator?
Calculators that have functions
such as trigonometric functions are generally called scientific
is a programmable calculator?
A programmable calculator is a scientific
calculator with algebraic memory functions.
is a graphing calculator?
A graphing calculator is a scientific
calculator with graphing functions.
is an OHP calculator?
An OHP calculator is see-through
so that it can be projected onto a screen through an overhead
projector. It is used by school teachers for classroom
activities and presentations at academic meetings.
is the D.A.L. system?
D.A.L. is the abbreviation for the
Direct Algebraic Logic system.
It is a way of inputting that follows the exact order
of the equation. Sharp was the first company to incorporate
this system into non-programmable scientific calculators
is the D.A.L. system different from V.P.A.M.?
V.P.A.M. can be found on Casio's
calculators and is essentially the same as Sharp's D.A.L.
Nowadays it has become standard to enter an equation as
it appears on the page.
should I pay attention to when buying a new scientific
Scientific calculators have many
functions. Therefore, you should know what functions are
needed today or in the future and whether the functions
in your field are included. Other factors, such as price,
durability and usability, should also be considered.
the functions and operating methods different between
educational and general scientific calculators?
Basically they are the same. Educational
calculators have functions that are helpful for education,
such as the D.A.L. system and the mathematical display.
are scientific calculators used in education?
Many students say they don't like
mathematics or science and find calculations difficult.
Scientific calculators reduce the burden of computation
and allow teachers to spend more time explaining theories
and showing fascinating aspects of mathematics, thereby
helping students become interested in mathematics. This
is why the use of calculators in classes and in tests
has been spreading world-wide.
me about cheating prevention and the model certification
In order to prevent cheating, some
schools ban programmable and graphing calculators that
can store formulas or functions that interfere with learning
the curriculum. These schools apply a certification system
to determine which calculators are appropriate for education.
Only models that conform to the certification can be selected.
