-62 means a number multiplied by itself twice
So in this case it is -6 x -6 = 36 - since -x- = +
If this was -6-2 the negative power means it's a fractional indice so first make it look like a fraction
1/-62 now it looks like a fraction (inverse) and the power mow looks like a normal square
Coz its still a negative number -6 x -6 = 36
So the answer is now 1/36

So when it is a minus power, first turn it into a fraction, then calculate as normal
Note: every number has a sign, it is either + or minus.
By convention, we always assume it is a plus unless stated otherwise.
To make sure u remember this fact put a plus sign in front of every number if no sign is showing
You can start with buses the 27 bus is +27
Its like if u say u have a car, what u really mean is you have 1 car. But u drop the 1 coz everyone takes for granted u meant 1 car, 1 house, 1 friend etc
Every power we assume its + unless otherwise stated.
So when a minus is put in front of the power, its saying make it a fraction first!
Maths is a game and games have rules.
This rule is a minus in front of power (indice) change to fraction form first!
So if it is 2-3 - the power -3 is saying turn it into a fraction first so
1/23 = 1/ 2x2x2 = 1/8
If it had of been 23 notice how no signs shown because we take for granted they r all +
Let's show them
+2+3 since it's a plus 3 we don't need to change it to a fraction and since it is a plus 2
We have +2 x + 2 x +2 and a +x+ x+ = +
2x2x2 = 8
Its easier to just do 23 = multiply the 2 by itself 3 times
2x2x2 = 8
When doing fractions of any type I prefer showing them as being more obviously top/bottom
1
-
2

Format and for that free hand is easier as typing is hard...lol
Ie
Numerator Denominator
When using a number that's a fraction it is better tro enclose it in brackets
As every indice is of the form - numberpower
The number can just as easily be a fractional number like a 1/3
So (1/3)2 is a third multiplied by itself
1/3 x 1/3 = 1x1/3x3 = 1/9
If it was (1/3)-2 then first u must get rid of the minus power by turning it into a fraction
1/(1/3)2
1/1/3 x 1/3
1/1/9
And 1 divided by a ninth =
1 to be cont - tired..lol

### How do you write 8.23 as a fraction

8 & 23/100 or 823/100
Since 23 is a prime number it can't be divided down, so that's as simple as that fraction can become.
If you're also doing rounding though, then it would become 8 & 25/100 or 8 & 1/4

### How do i change a fraction into a ratio that does not have a denominator of 100?

You're on the right track!

920 92 46 23
------ = ---- = ---- = ---
1000 100 50 25

Now we can't go any further, because 23 is prime.

Good luck.

### How to convert this to fractions 12 1/6 - 2 3/8 -7 2/3 + 19 3/4

One way to solve the problem is to convert all the fractions so that they have the same common denominator, then just add them up.

12 1/6 = 73 / 6 = 292 / 24

2 3/8 = 19 / 8 = 57 / 24

7 2/3 = 23 / 3 = 184 / 24

19 3/4 = 79 / 4 = 474 / 24

Therefore:

(292 / 24) - (57 / 24) - (184 / 24) + (474 / 24) = 525 / 24 = 21 21/24 = 21 7/8

Therefore:

12 1/6 - 2 3/8 -7 2/3 + 19 3/4 = 21 7/8

Good luck, I hope that helps.

### What is the value of 12 1/6 - 2 3/8 -7 2/3 + 19 3/4?

12 1/6 = 73 / 6 = 292 / 24

7 2/3 = 23 / 3 = 184 / 24

19 3/4 = 79 / 4 = 474 / 24

Therefore:

(292 / 24) - (57 / 24) - (184 / 24) + (474 / 24) = 525 / 24 = 21 21/24 = 21 7/8

Therefore:

12 1/6 - 2 3/8 -7 2/3 + 19 3/4 = 21 7/8

Good luck, I hope that helps.

### How do i convert 1.695652174 on TI-84 plus edition. i already try doing math key but it won't convert into fraction and keeps giving me same answer.

Answer is 39 over 23......or 1 and 16/23. Check your settings on the calculator. People are running into this problem with decimals and there is an easy fix.

Let's say you have a repeating decimal such as .16666.....If you type in .166 or .1666 or .16666 and check as fraction it will NOT work. Reason why is you haven't typed enough of the "repeating" numbers for the calculator to understand that it is in fact "repeating." If you have a single number ie. 1-9 you must type in a minimum of 11 of that number. Then it WILL work as fraction.

Let's say you have a 2-digit number such as 13. Then you need to type in at least 6 of that number. Say you want to convert 1.2181818 where 18 keeps "repeating." Well I only typed it in 3 times. It won't work to convert. But type in that repeating number 6 times and it will.

Again calculator need to know that it is in fact repeating. Only typing it in a couple times could still change the outcome so it will basically fail to show the fraction until it knows for sure.

### How do I input a mumber in scientific notation?

The structure of a number in scientific notation is as follows
one digit [decimal mark] several digits power of 10 (- sign if needed) up to two digits for the exponent.
d.ddddd [10^] (-) dd

To enter a number in scientific notation you need to use the [EXP] key, between the [.] and the [=] sign, on the bottom row of keys.

Ex: Avogadro's number (do not worry if you do not know what it represents)
Na= 6.02 x10 ^23
6.02 [EXP] 23 [=]

Electron charge 1.6 x10 ^(-19)
1.6 [EXP] [+/-] 19 [=]
The [+/-] key is the change sign key, in the first column of keys, between the fraction key [a b/c] and the [7] key

### Step by step ho to Convert Fractions to decimals?

No post is an adequate substitute for reading the manual. Here is the meaning of some of the primary keys.
1. hyp.: To calculate hyperbolic functions: hyp + sin calculates the hyperbolic sine, hyp + cos calculates the hyperbolic cosine, hyp + tan calculates the hyperbolic tangent (sinh, cosh, tanh)
2. sin. To calculate the sine of an angle
3. cos.To calculate the cosine of an angle
4. tan. To calculate the tangent of an angle
5. yx : y with raised x, calculates general powers
6. ln: calculates the natural logarithm (log in base e)
7. log: calculates the logarithm in base 10
8. ab/c : used to enter mixed fractions; 13 ab/c 7 ab/c 5 enter the mixed fraction 13 and 7/5
9. x10 to the X : calculates the exponential function on some calculators. used to enter powers of 10 as in scientific notation; 6.02x10^23 is keyed in as 6.02 EXP 23 (Avogadro's Number of Chemistry and Physics)
10. (-).: This is the change sign. It negates the value of a number. If a result is positive it makes it negative, and if it is negative it makes positive
11. deg ' " : used to convert between decimal degrees and degree, minute, second.
12. rcl : used In conjunction with a memory location, recalls the contents of the memory ( if there is one memory M, extracts what is in M and displays it)
13. sto: used in conjunction with the name of a memory register, stores a result or an entry in the relevant memory.
14. M+ adds the content of the display to the constant memory M

### Entering 6.02 X 10^23/ 206 =

I think I'm reading this correctly. In your exponent, you are dividing 23 by 206. If so, enter in the calculator the following way:

6.02 x 10 ^(23/206) and then the enter/= key. You should get an answer of 8. The ^ key is 4 keys above the "on" key. You must use parentheses around the fractional exponenet
