Abstract

A new calculator allowing counting vertically, to aid understanding of child learning arithmetic. Within the keyboard is the complete modern Key board with the usual ten numbers, however the numbers are not the usual 3 by 3 plus Zero configuration but two lines of five numbers one upon the other. When fully learned, the child will truly understand the basic working of Mathematics. Junior school children who are Years 8. 9 and 10. are taught to adding in columns, therefore, having a calculator that also counts in columns is a must. This system is easy to use and will make counting through Zero easy to understand.

Description

A calculator for Junior and secondary children.

This calculating machine contains two calculators The large keyboard is for the use of children of Junior school age, The small Keyboard is for the use of children of secondary school age In fact both keyboards are perfect for the use of secondary school children.

Junior school children who are Years 8. 9 and 10. are taught to adding in columns, therefore, having a calculator that also counts in columns is a must.

This Vertical counting calculator does just that it counts in columns.

This Large vertical counting Keyboard for young children enables them to Add, subtract, Multiply and Divide, by this using this new calculating machine, young children will speed up their calculation and this will be a boon not only for the confidence of the children but the pleasure of their parents too.

Children in Junior school count in columns, example at the age of ten they are able to add up Numbers in three columns example HUNDREDS TENS AND UNITS

THREE LINES HIGH

Or perhaps FOUR LINES HIGH. at the very most they will count no more then TWELVE NUMBERS and so the normal calculator makes little sense in fact it makes no sense to children of that age.

Secondary school children will use both systems of calculation, however, They will start to learn to use the new vertical calculator and then with practice will be able to use the normal every day calculator with the new number pad.

The Vertical counting calculator counts in columns, therefore children will quickly understand how to use the keys, children may use all the 65 numbered keys, and with practice they may be able to pick the appropriate minus Number key below the Zero line. When the count passes through the Zero line, the speaker will sound to inform he or she that they have now passed through Zero and the child should now put their fingers on the plus keys above the Zero line and carry on counting until the final answer is arrived at.

The small number pad acts as a normal calcultor but the keys are in another new configuration, not the 3x3 plus Zero as in the normal keypad But a new number Keypad where the numbers are placed in two lines one above the other example:- 34567/89012 with the Zero in the middle of the bottom of the bottom line.

Children in Junior schools can learn to add one number to another and at eleven they can count four columns of HUNDREDS TEN AND UNITS This is to prepare the young children for when they enter Secondary Education, when these children start to use a normal calculator or perhaps the calculator with the new number keypad.

The 65 Keys of the large key board is for vertical calculation Ideal for the use of young children of eight, Nine and Ten years of age By using the vertical Keys of the calculator, they will find it easy to count in columns. 2.

1/3 This drawing shows the a complete keyboard within which are 31 plus keys for calculation in positive numbers, these are located above the black zero tine, notice on the Zero line there are three Zero Keys, Below the black Zero line are 31 minus keys for calculation in negative numbers. Naturally when calculation is from a negative number through Zero and finishing above the Black Zero Line, you decide on the number a negative number and by touching the keys the young child is able to count through Zero and finish on a positive key.

2/3 This drawing shows a plus keyboard with 31 keys plus 3 Zero keys this calculator is uncomplicated and easy to use. Both calculators stand out, thus giving the children the ability to multiply and divide with ease. Therefore these two calculators are easy to read and use.

3/3 This drawing shows a minus keyboard with 31 Minus keys and 3 Zero keys This calculator is made to subtract and divide, This too is easy to for the young children to like mathematics.
