SOURCE: I just want to find out how to use the simple

Usually you enter the first number then you press the key ( +, -, x or /) corresponding to the operation you want to perform and you press the equal sign (=).

ex: 15+3=18

Often you can perform the operations one after the other without bothering with the intermediate results. You can do so **provided you respect the priority rules:** parentheses,powers, multiplication/division, addition/subtaction...)

Hope it helps

Hello,

To raise a number to some power other than 2 or 3, you use the [y to the x] key. Exemple 2[y to the x] 5 = 2x2x2x2x2=32.

Hope it helps.

PS. I could not understand what you wanted with those expressions.

Press MODE to bring up the mode screen. Use the arrow keys to move down to the line beginning "Real". Highlight either "a+bi" or "re ^ theta i" depending on whether you want to work in rectangular or polar coordinates, then press ENTER to save the change. Press 2ND [QUIT] to exit the mode screen.

This
post is rather exhaustive as regards the matrix capabilities of the
calculator. So if the post recalls things you already know, please skip
them. Matrix multiplication is at the end. As to division of matrices, I do not believe that this operation exits.

Let me explain how to create matrices. (If you know how to do it, skip
to the operations on matrices, at the end.)

First you must set
Matrix calculation

[MODE][6:Matrix]. Then By entering one of the numbers [1:MatA] or
[2:Matb] or [3:MatC] you get to choose the dimensions of the matrix

(mxn]. Once finished entering the matrix you clear the screen.

The operations on matrices are available by pressing [Shift][Matrix]

[1:Dim] to change the dimension of a matrix (in fact redefining the
matrix)

[2: D A T A] enter values
in a matrix

[3:MatA] access Matrix A

[4:Matb] access Matrix B

[5:MatC] access matrix C

[6:MatAns] access the Answer Matrix (the last matrix calculated)

[7:det] Calculate the determinant of a matrix already defined

[8:Trn] The transpose of a matrix already defined

To add matrices MatA+MatB (MUST have identical dimensions same m and same n, m and n do not have to be the same)

To subtract MatA-MatB. (MUST have identical dimensions, see above)

To multiply MatAxMatB (See below for conditions on dimensions)

To raise a matrix to a power 2 [x2], cube [x3]

To obtain inverse of a SQUARE MatA already defined MatA[x^-1]. The key [x^-1] is the x to
the power -1 key. If the determinant of a matrix is zero, the matrix is singular and its inverse does not exit.

Dimensions of matrices involved in operations must match. Here is a
short summary

The multiplication of structured mathematical
entities (vectors, complex
numbers, matrices, etc.) is different from the multiplication of
unstructured (scalar) mathematical entities (regular numbers). As you
well know matrix multiplication is not commutative> This has to do
with the dimensions.

An **mXn **matrix has** m rows **and**
n columns**. To perform multiplication of an **kXl** matrix by
an **mXn** matrix you multiply each element in one row of the first
matrix by a specific element in a column of the second matrix. This
imposes a condition, namely that the number of columns of the first
matrix be equal to the number of rows of the second.

Thus, to be
able to multiply a kXl matrix by am mXn matrix, the number of columns of
the first (l) must be equal to the number of rows of the second (m).

So**
MatA(kXl) * MatB(mXn) is possible only if l=m**

MatA(kX3) *
Mat(3Xn) is possible and meaningful, but

Mat(kX3) * Mat(nX3) may not
be possible.

To get back to your calculation, make sure that the
number of columns of the first matrix is equal to the number of rows of
the second.** If this condition is not satisfied, the calculator
returns a dimension error**. The order of the matrices in the
multiplication is, shall we say, vital.

Hi Anonymous,

You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount, but only multiply or divide, never add or subtract, to get an equivalent fraction.

I've only shown the fraction part of your question as 1 is a whole number.

1/2 = 2/4, or 4/8, or 8/16 or 16/32 or 32/64 & so on.

Going the other way, dividing 2/4 by 2 will give 1/2.

But, only divide when the top and bottom would still be whole numbers, for instance you wouldn't use divide for odd number fractions, for example 1/3 or 3/5 etc.

Trust this helps, best regards Alan

Your calculator may have a solver of equations, which you activated. It is prompting you to enter the coefficient a. Is there a question mark after the a?.

Is it complex or matrix? You can have only one mode at a time.What kind of equations? The solve function uses real-valued equations.

Complex numbers: You can add, subtract, multiply and divide. You can convert a number from rectangular to polar forms and vice-versa; you can calculate the absolute value of a complex number, or a conjugate.

All the operations are done in the Mode CMPLX.

Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."

If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.

Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

MOD simply calculates the remainder that is left over after dividing by the MOD parameter.

For example, 10MOD7 = 3 since you can only divide 7 into 10 once, leaving a remainder of 3.

For larger numbers, eg 389487MOD31 you start by dividing 389487 by 31, which gives 12564.09677 (on the display), however you only want the fractional part so subtract 12564 to give 0.0967741935 . This includes the lower value digits that were previously hidden. Then multiply this result by 31 which gives 2.999999999 on the display. Since the result of a MOD calculation has to be a whole number, the answer needs to be rounded to 3. If the answer doesn't easily round to a whole number, it is likely that you have gone beyond the calculators working capacity.

An alternative method is to take the integer part of the first result (12564) and multiply it by 31 to get 389484, then subtract this from 389487, giving the answer of 3.

The following solution shows how to find the value of x:

Start with the general equation given:

y = -(3/5)x - 8

Substitute the known value of y:

-11 = -(3/5)x - 8

Add 8 to both sides:

-11 + 8 = -(3/5)x - 8 + 8

-3 = -(3/5)x

Now multiply both sides by 5 to get rid of the denominator:

-3 * 5 = -(3/5)x * 5

-15 = -3x

Now divide by -3 to get x:

-15/3 = -3x/3

x = 5

The answer is x = 5.

Start with the general equation given:

y = -(3/5)x - 8

Substitute the known value of y:

-11 = -(3/5)x - 8

Add 8 to both sides:

-11 + 8 = -(3/5)x - 8 + 8

-3 = -(3/5)x

Now multiply both sides by 5 to get rid of the denominator:

-3 * 5 = -(3/5)x * 5

-15 = -3x

Now divide by -3 to get x:

-15/3 = -3x/3

x = 5

The answer is x = 5.
