+                <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>
