+                <p class="blog_content">The image above is an example of a table we can use to convert <span class="moreInfo">8-bit binary numbers<span class="extraInfo">referred to as bytes</span></span> to denary.
+                    Each individual bit is put into each column in the same order as written. Any columns with a 1 should have their values added together. 
+                    The resulting value is the denary conversion.
+                    
+                    To convert from denary to binary, take the number you wish to convert and starting in the left most column try subtracting the number from 
+                    the one you wish to convert. If it can be done without producing a negative put a 1 in the column, if you cannot, put a 0. Once the remainder is 0,
+                    add 0s to any remaining columns. The resulting number is the binary conversion.
+                    
+                    If you want to convert above 8-bit numbers, each column's denary value is calculated as 2 raised to the power of the column starting from the right and at 0.

+                <p class="blog_content">In primary school we are taught to use long addition to sum numbers on paper. The practice relies on the concept of carrying digits to
+                    other columns when the simple addition excedes 10. We can use the same technique to add binary numbers just instead of carrying when
+                    exceding 10, we do this at 1. The best way to visualise this is with a couple of rules whenn carrying. First, when adding two 1s in a column,
+                    the answer is 0 carry 1. Secondly, when adding three 1s in a column (from a previous carry), the answer is 1 carry 1.</p>

+                <p class="blog_content">Subtraction in binary is a little hard as it is not as intuitive as the addition. To subtract two binary numbers we use a method known as
+                    2's complement. 2's complement is a way of expressing a binary number as a negative. After doing this conversion, you can just add the two
+                    numbers and it will give the same answer as if the two numbers were subtracted in denary. To find 2's complement, you begin by inverting 
+                    each bit in the number (if the bit is a 0 it becomes 1, and vice versa) and then add 1.</p>

+                <p class="blog_content">Hexadecimal is another base system used in programming. Just like binary and denary hexadecimal creates a new column when it's 
+                    limit is reached (15). However, as the base system is higher than our standard system (denary), we use letters (A-f) to express the 
+                    numbers 10-15 so that they can be single digits.</p>
+                    
+                    <p class="blog_content">To convert from binary to hexadecimal, split the 8-bit number into two 4 bit numbers and convert these numbers to denary. For any number 
+                    greater than 9 remember to use the letter assignation for hexadecimal. To convert from binary to denary, take the left digit and multiply
+                    it by 16, then add the second digit. If you want to convert hexadecimal numbers with more than two digits to denary, you take each digit
+                    and multiply it's denary value by 16 raised to the power of digits left to convert. The easiest way to convert from denary to hexadecimal
+                    is by first converting to binary, and then hexadecimal.</p>
