People perceive maths as a difficult course with tough numbers to derive.

positive numbers are always positive numbers and negative numbers are always negative numbers

The problem comes when you start using combinations in maths

So basically

+ x+ = +

+ x- = -

- x- = +

get a good maths book and read it up.

Both numbers are multiple of 100 (the two zeros at the end). Divide both numbers by 100 (remove two zeros from each). You are left with 20/6. Now divide each number by 2 to get 10/3. Use the technique you learned to calculate the result.

Somehow you're calculating 12!/(5!/7!).

Press 1 2 MATH left-arrow 4 / 5 MATH left-arrow 4 / 7 MATH left-arrow 4 ENTER to calculate the desired value. Alternatively, you can press 1 2 MATH left-arrow 3 5 ENTER or 1 2 MATH left-arrow 3 7 ENTER to calculate the same thing.

For negative numbers (not just exponents), make sure you use the (-) key just to the right of the decimal point key, not the - key for subtraction.

For what follows I'm going to assume you have at least version 2.53 of the operating system for the 84Plus. If you have an older version, I STRONGLY recommend you update it:

http://education.ti.com/educationportal/sites/US/productDetail/us_os_84plus.html

You can use the "n/d" command in the MATH/NUM menu to enter the division bar. For example, to enter 1/2, press 1 MATH right-arrow ALPHA [D] 2 ENTER. If you just want the number, you can also enter it as 1 / 2.

You can convert a decimal number to a fraction using the >Frac command in the MATH menu. For example, to convert 0.2 to a fraction, press . 2 MATH 1 ENTER.

For cube roots, use the cube-root function in the MATH menu. For example, to calculate the cube root of 8, press MATH 4 8 =

For other roots (including cube root), use the xth-root function in the MATH menu. For example, to calculate the fifth root of 32, press 5 MATH 4 3 2 =

Your teacher has 64 old math books.

Define the variables:

n = the total number of books x + y = the number of books divided into two groups (x being one set of books and y the other)

Equation set-up from the problem:

64(x - y) = x^2 - y^2

Work it out:

64(x - y) = (x + y)(x - y)

__64(x - y)__ = __(x + y)(x - y)__
(x - y) (x - y)

64 = (x + y)

Therefore, 64 = n

Hi,

You can write a fraction by dividing an integer number by another but it will not be displayed as you enter it. It becomes a decimal number.

However, if you want to keep it in fraction form (but reduced to its simplest form) you use the command [|=>Frac] . The arrow is a short, fat one.

To access the command

Press [MATH][1:ToFrac] [ENTER]

Ex: you enter 27/48 [MATH][1:ToFrac][ENTER]

Calculator displays 9/16

So you can keep numbers (in reduced form) by inserting [MATH][1:ToFRac] before pressing the [ENTER] key.

Hope it helps.

Thank you for rating the solution.

Hello,

You get access the command by pressing [MATH][1: |->Frac].

If you want enter a fraction and keep it as a fraction (albeit a reduced one)

key in the number then the sequence [MATH][1: |->Frac]., then [ENTER].

Practice : 27/48 [MATH][1: |->Frac] [=] gives the reduced form 9/16.

While this fraction is still in [ANS] memory, you can press [MATH][2: |->Dec] [=] to get the decimal value 0.5625

Hope it helps.

Hello,

There is no fraction button. Any division of two integers you do is represented as a decimal number. If you want your fraction to remain a fraction you enter it as follows

**7[ / ] 19 [ MATH][1:ToFrac] [=] displays 7/19**

If you want to convert a decimal number into a proper fraction press**[MATH][1:ToFrac] .**

Exemple 7/19 [ENTER] gives .36842105. If without doing anything else, you press [MATH][1:ToFrac] you recover 7/19.

There are limitations related to the number of decimal digits in the floating point number.

.3684 [MATH][1:ToFrac][=] gives 921/2500 but

.36842 [MATH][1:ToFrac][=] gives .36842 : it is not converted to fraction.

Hope it helps
