BILANGAN HABIS DIBAGI ... ( 1 )


BILANGAN HABIS DIBAGI

2 
jika angka terakhir adalah habis dibagi 2.
Suatu bilangan habis dibagi 2, ciri-cirinya adalah bilangan yang berakhiran (berangka satuan) 0, 2, 4, 6, 8. Dengan kata lain bilangan itu adalah bilangan genap.

Contoh: apakah 74 habis dibagi 2? Karena 74 merupakan bilangan genap (Ingat rumus untuk bilangan genap. Rumus untuk bilangan genap adalah 2k untuk sebarang k bilangan bulat. Sedangkan untuk bilangan ganjil yaitu 2k-1 untuk sebarang k bilangan bulat). Karena 74 memenuhi rumus bilangan genap, maka 74 habis dibagi 2. 74 : 2 = 37


3
jika jumlah angka-angkanya habis dibagi 3.
Jumlah digit-digitnya habis dibagi 3

Contoh: Apakah 213 habis dibagi 3? Akan kita jumlahkan digit-digit pada bilangan 213. Didapatkan, 2 + 1 + 3 = 6. Karena 6 (hasil dari penjumlahan digit-digitnya) habis dibagi 3. Maka bilangan itu (213) habis dibagi 3. Apakah -345 habis dibagi 3? Langkahnya sama. Kita jumlahkan digit-digitnya dan menghiraukan tanda negative. Jangan tertipu oleh tanda negatif.

4 
jika bilangan dari dua angka/digit terakhir habis dibagi 4.
Lebih mudahnya yaitu puluhan dari bilangan itu habis dibagi 4.

Contoh : Apakah 324 habis dibagi 4? Dua digit terakhir yaitu 24. Dan 24 habis dibagi 4. Sehingga 326 habis dibagi 4. Apakah 2006 habis dibagi 4? Tidak. Karena dua angka terahirnya yaitu 06. Sedangkan 06 tidak habis dibagi 4. Sehingga 2006 tidak habis dibagi 4.
Bukti ditinggalkan sebagai latihan. Tips untuk membuktikan, langkah yang digunakan hampir sama dengan pembuktian bilangan habis dibagi dua. Hanya saja nantinya memakai angka 100. Karena 100 habis dibagi 4, sedangkan 10 tidak habis dibagi 4.


5
jika angka terakhir 0 atau 5

Contoh : Apakah 3255 habis dibagi 5? Digit terakhir adalah 5.
Sehingga 3255 habis dibagi 5. Apakah 2005 habis dibagi 5? Sangatlah mudah menentukan ciri bilangan habis dibagi 5.

6
jika habis dibagi 2 dan 3.
Ciri bilangan yang habis dibagi 6 adalah bilangan genap yang jumlah angka-angkanya habis dibagi 3. Atau bilangan yang habis dibagi 3 dan habis dibagi 2.

Contoh : apakah 234 habis dibagi 6? Sekarang kita perhatikan jumlah angka-angkanya. 2+3+4=9. Dan 9 habis dibagi 3. Karena jumlah angka-angkanya habis dibagi 3 dan bilangan itu genap. Maka 234 habis dibagi 6. Kita juga bisa mengatakan bahwa jika bilangan habis dibagi ab, maka bilangan itu habis dibagi a dan habis dibagi b. 


7
Bila bagian satuannya dikalikan 2, dan menjadi pengurang dari bilangan tersisa. Jika hasilnya habis dibagi 7,
maka bilangan itu habis dibagi 7.

Contoh: apakah 5236 habis dibagi 7? Kita pisahkan 6 (satuannya), kemudian 523 – (6 x 2) = 511. Apakah 511 habis dibagi 7? 51 – (1 x 2) = 49. Karena 49 habis dibagi 7
maka 5236 habis dibagi 7.


8
Tiga digit terakhir habis dibagi 8.

Contoh : apakah 2168 habis dibagi 8. Iya, karena 168 habis dibagi 8.


9
Jumlah angka-angkanya habis dibagi 9.

Contoh : apakah 819 habis dibagi 9? Jumlah digit-digitnya yaitu 8 + 1 + 9 = 18. Dan 18 habis dibagi 9. Sehingga 819 habis dibagi 9.


10
Tentu saja bilangan yang digit terakhirnya (satuannya) adalah 0.

Contoh : 77763862974620 habis dibagi 10 karena satuannya adalah 0.

Typing the equation ( Microsoft Word )

https://uwaterloo.ca/

Typing the equation


To enter the equation, just start typing. All keyboard characters can be entered directly. (Parentheses, brackets and braces can be entered from the keyboard, but these are fixed in size. Brackets that will "grow" must be selected from the appropriate template).

Entering symbols

There are 10 symbol palettes, the entire top row of buttons. The symbols printed on the buttons provide a clue to the characters available under each button. The two rightmost symbol palettes are (1) the lower case Greek letters, and (2) the upper case Greek letters.

To select an item from a symbol palette, click on the palette button, and then click on the desired character.

Entering templates

The second row of palette buttons are template palettes. They provide place holders for entering information.

Moving around the equation

A flashing right angled cursor indicates where you are about to enter information on the equation. The horizontal bar of the cursor marks the base line of the symbols to be entered. The vertical bar indicates the height. You can set the insertion point by clicking with the mouse, or with the keyboard.

Creating Mathematics inside Microsoft Word


Notes:
 On your home machine you probably will need to load your Microsoft office CD and do a custom install to install the Equation Editor. After installing you may need restart your microsoft word.


Insert Equation

To insert an equation, choose Insert, Object, Microsoft Equation 3.0, and click OK . One of 2 things will happen:
  • A highlighted area will appear, along with equation editing palettes. This is known as in-place editing. It can be very difficult to see what is being entered, or
  • A separate window will open, with the palettes on top. This is much easier for entering equations. This looks like the following.

Customize Toolbar

If you are entering many equations, you may find it convenient to have an "Insert Equation" button right on the toolbar. This can be done by:

  1. right clicking on the tool bar (or opening the Tools menu) and choosing Customize
  2. A window will open. Click on the Commands tab if it is not already selected.
  3. Select Insert on the left and then Equation Editor on the right.
  4. Click and drag the button beside Equation Editor (a square root symbol with an alpha in it) to the toolbar. From now on, clicking on that button will insert an equation.

Shortcuts Keyboard

General

  1. Always add a full space before and after an equal sign, before and after a plus or minus sign, after a limit sign or integral sign, and before each limit on a definite integral. A full space is created inside an equation box by pressing  Ctrl+Shift+Space Bar.
  2. Always add a half space between a coefficient and a variable and before and after the arrow sign in a limit. A half space is created by pressing Ctrl+Space Bar.
  3. To insert a tab character in a slot, press CTRL+TAB.
  4. To line up your equal signs you need to use the format/align option.
  5. You can add text inside an Equation box by selecting Style - Text from the toolbar menu.

x^n             xn
(x+x)^n         (x+x)n
x^(n+n)         x(n+n)
x^n+n           xn+n

Division
x/n            "x" divided by "n"
(x+x)/n        "x" plus "x" total divided by "n"
x/(n+n)        "x" divided by the sum of "n"+"n"
x/n+n           "x"divided by "n" total plus "n"

Integrals: be sure to type spaces as indicated
\int  x dx             boundless integral over the function x
\int _0^n x dx         integral with bounds zero to n over the function x
\int _0^(n+n) x dx     integral with bounds zero to n plus n all over the function of x
\iint x dx             double integral with no bounds
\iiint  x dx           triple intertal
(I am not sure if you can add bounds to all the integrals
 I would use multiple single integrals for this as shown below)

\int_0^2\pi \int _0^pi \int _0^r r^2 sin \phi dr d\phi d\theta
bounds from 0 to 2(pi), 0 to pi and 0 to r
(this is an integral for a sphere of radius r)

How to use Alt Codes ?


  1. Find the Alt Code you need from the alt code tables on this site or from the downloadable Alt Code list.
  2. Make sure that "Number Lock" is switched on.
    There should be a light on your keyboard indicating this.
If not, press the "Number Lock" key at the top left of the numeric keypad.



  • Hold down the "Alt" key to the left of the space bar and key the code on the numeric keypad.
    Don't release the "Alt" key until after you've typed the alt code. When you release it you should see the special character you include.
  • Instructions for entering Alt Codes on a lap top
    Even if you have a laptop or a keyboard with no numeric keypad - you can still use alt codes.


    1. Look for a "function" or "fn" key normally near the bottom left of the keyboard.
    2. Look for a button with "num lock" written in the same colour which is usually near the top right of the keyboard.


  • While holding "function" press and relase "num lock".
  • Enter alt codes using the method above but to enter the actual numeric alt code use the keys with numbers in the same colour as the function (fn) key. Normally "U" has 4 on it for example.
  • Switch "num lock" off in the same way as you switched it on to continue using your keyboard normally.

  • Character Map

    Open Character Map by clicking the Start button , clicking All Programs, clicking Accessories, clicking System Tools, and then clicking Character Map.

    Using Character Map

    1. In Character Map, click the Font list, and then click the font you want to use.
    2. Click the special character you want to insert into the document.
    3. Click Select, and then click Copy.
    4. Open your document and click the location in the document where you want the special character to appear.
    5. Click the Edit menu, and then click Paste.
