Question about Computers & Internet

It is a number of dots which can form an equilateral triangle when so arranged. So these numbers are 1 (trivial), 3, 6, 10, 15, 21, ....n(n+1)/2 where n is the n'th triangle number eg the 4th triangle number is 4(5)/2 = 10 as above

99.9999 repeating is technically equivalent to 100, depending on what level math you're in.

For example, 100 / 3 = 33.3333...

but clearly 33.333 * 3 = 99.9999...

So multiplying both sides of my first equation by 3, we get 100 = 99.9999

If you are not looking for "a number equivalent to 100" but "an equation or set of numbers equivalent to 100", then there are many ways. For example:

99 + 9/9 = 99 + 1

And 99 + 1 = 100

For example, 100 / 3 = 33.3333...

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

Pay more attention in math class, do your daily homework or tutorials. If you do not understand the chapter or any math problems, just ask the math teacher directly. He or she is the best bet that can help you directly dealing with your situation.

Just don't forget "In any examinations, it is a test of what you don't know".

even nos: 2,4,6

prime nos:2,3,5

ie 1 is the only no. which is not desired

probability of getting one=1/6

hence probability of getting either even or prime no is

= 1-1/6 = 5/6

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
