The Multiple-Algebraic Calculator

The Multiple-Algebraic Calculator demonstrates that a number of complex calculations (involving 24 unknowns, calculus, and trigonometry) can be carried out simultaneously, by devices created with specialized design concepts in the JavaScript or spreadsheet formats. When the user enters 12 numbers, and left clicks with the mouse, the Multiple-Algebraic Calculator initially solves: AX+BY+KZ=M, DX+EY+FZ=N,GX+HY+JZ=W for X, Y and Z. With the calculated values for X, Y, and Z, and the numbers entered by the user, additional sets of calculations are automatically carried out involving six double integrals, ratios, algebra and trigonometry.

Instructions

To use the Multiple-Algebraic Calculator enter twelve numbers in the twelve white input boxes, below. (To enter or delete numbers, left click with the mouse on the relevant white input box.) For calculated results left click with the mouse on the background Alternatively, with the online JavaScript version you can press the calculation button, and with the spreadsheet version you can press the enter key. Numbers and words displayed in red type are calculated results.

Note: If less than 12 numbers are entered this Calculator will NOT function properly. All twelve input boxes must contain numbers entered by the user.

To see all the equations, double integrals, trigonometry and calculated results, scroll down. The Multiple-Algebraic Calculator is approximately 20 times the height of a typical computer screen. It is equivalent to a 15 page document.

The Multiple-Algebraic Calculator has a number of error-checking devices (above and below).

These devices check the calculations and the numbers you entered to determine if they satisfy

the equations. These devices provide feedback in words or numbers. The calculations for

all of the error-checking devices are rounded to

decimal places. You can change this,

by deleting the blue number above, and entering the number of decimal places you prefer. If you enter a number that is too high you may get false indications of errors.

Note: The number of zeros displayed is not affected by the blue number.

Spreadsheet formula for X is =(M-(B*Y+K*Z))/A

Spreadsheet formula for Y is =(A*N+D*K*Z-A*F*Z-D*M)/(A*E-D*B)

Spreadsheet formula for Z is

The Multiple-Algebraic Calculator displays a summary of

calculated results for 24 unknowns, below. This list does not

include all the calculated results. For all the results scroll down.

Calculated results on this list are rounded to

A Ratio Problem Involving only X as an Unknown

In this section: the equations AX+BY+KZ=M, DX+EY+FZ=N, and

GX+HY+JZ=W and unknowns X, Y, and Z are converted into a ratio

problem, with only one unknown, X. This is possible because the

values for X, Y and Z have been calculated.

If P*X=Z

If V*X=Y

then P=Z/X

then V=Y/X

In terms of numbers

P*X=

V*X=

Thus, all of the unknowns represented

by Z can be replaced by P*X

by Y can be replaced by V*X

The three equations (AX+BY+KZ=M, DX+EY+FZ=N, GX+HY+JZ=W)

can now be rewritten in terms of X, as follows:

AX+BY+KZ=M

DX+EY+FZ=N

GX+HY+JZ=W

In terms of X

AX+BVX+KPX=M

DX+EVX+FPX=N

GX+HVX+JPX=W

The above conclusions and calculations can be checked as follows:

AX+BY+KZ =

AX+BVX+KPX =

DX+EY+FZ=

DX+EVX+FPX=

GX+HY+JZ=

GX+HVX+JPX=

AX+BY+KZ=M rewritten in terms of X is AX+BVX+KPX=M

This can be restated in the form of a word problem as follows:

There are three numbers in the ratio of A, B*V, and K*P,

and the sum of the three numbers is M.

In terms of calculated data the three numbers are in the following RATIOS:

A =

B*V =

K*P =

The three numbers are as follows:

A*X =

B*V*X =

K*P*X=

The sum of the numbers is:

The above should equal M =

DX+EY+FZ=N rewritten in terms of X is DX+EVX+FPX=N

This can be restated in the form of a word problem as follows:

There are three numbers in the ratio of D, E*V, and F*P,

and the sum of the three numbers is N.

In terms of calculated data the three numbers are in the following RATIOS:

D =

E*V =

F*P=

The three numbers are as follows:

D*X =

E*V*X =

F*P*X=

The sum of the numbers is:

The above should equal N =

GX+HY+JZ=W rewritten in terms of X is GX+HVX+JPX=W

This can be restated in the form of a word problem as follows:

There are three numbers in the ratio of G, H*V, and J*P,

and the sum of the three numbers is W.

In terms of calculated data the three numbers are in the following RATIOS:

G =

H*V =

J*P=

The three numbers are as follows:

G*X =

H*V*X =

J*P*X=

The sum of the numbers is:

The above should equal W =
