HTML Basics

When creating a web page with html, this is the basic structure. All highlighted are notes and are not necessary.

<!DOCTYPE>
<html>
<body>

</body>
</html>


After this, you can add a heading and a paragraph.

<!DOCTYPE>
<html>
<body>

<h1>This is The Heading</h1>

<p>This is the paragraph</p>



</body>
</html>

Note that you end with a forward slash. You can add onto this by centering your heading and adding a pagebreak which separates the heading from the paragraph. You can make notes with //. 

<!DOCTYPE>
<html>
<body>

<h1><center>This is The Heading</center></h1>
<hr> // This is the page break 

<p>This is the paragraph</p>


</body>
</html>

Binary (Base 2)

The world works on base 10 numbers but computers and telephones on the other hand use base 2 (binary). In some stage of school, you will have to learn base numbers. This post hopefully will explain to you how binary works. Anything to the power of 0 is 1.

Let's start with a basic base 10 number, say 35

35: (32+2+1) = 35. All other place holders are a 0.


 26 (64)
25 (32)
24 (16)
23 (8)
22 (4)
21 (2)
20 (1)

 1
 0
 0
 0
 1
 1


Let's try a slightly harder number, say 112.

 112: (64+32+16) = 35. Once again all other place holders are a 0
 26 (64)
25 (32)
24 (16)
23 (8)
22 (4)
21 (2)
20 (1)
 1

What Is A Colloid?

A colloid is between a solution and a suspension. A colloid is formed when the particles are larger than the particles in a solution, yet smaller than the particles in a suspension (particle of the solute).

There are 6 different types of colloids: emulsions, sols, foams, gels, smokes, mists

Emulsion - particles of liquid are spread throughout another liquid e.g. milk

Sol - particles of a solid spread throughout a liquid e.g. blood plasma

Foam - gas mixed with a liquid e.g. shaving cream

Gel - liquid particles are held between particles of a solid e.g. jelly

Smoke - when a solid is spread throughout gas e.g. carbon + air

Mist - liquid spread throughout a gas e.g. fog

These are the 6 different types of colloids.
PLEASE comment.

Factor Tree and Prime Notation

FACTOR TREE

For example 68 and 108:
     
      68                                                   108
    2     34                                           2       54
         2      17                                            2    27
                                                                     3    9
                                                                         3   3       must divide with prime number
                                                                        

This helps with finding the HCF and LCM. 

The factors which are the same are multiplied with each other. {2x2} The highest common factor is 4.

To find the LCM, you must multiply the highest powers of each number. Therefore the lowest common multiple is 2x2x3x3x3x17. This is 1836.

This is what you do when they ask you to answer questions in index notation. Instead of writing 2x2 for example, you must write 2 (with indices) to the power of 2. 


The 'Box' Technique

This is a technique used for questions where you have to find out how many things does one person has compared to others.

Simple Question:
Sally had 12 ducks. Bill has x3 more ducks than Sally. Jerome has 18 ducks less than Bill. 

S {12}
B {36} 12x3
J {18}  12x3-18

This is a really simple question - you do not need to use this technique for this.
When you get to harder questions, this is useful.

12 is one whole therefore counting as one 'box'.
12x3 is 3 boxes
12x3-18 is 3 boxes minus 18.

Easy and neat way to answer these questions.
