Essay of robotics:The importance of Asimov's laws of robotics and what happens if the robots broke it.

What is robotics is a programmable mechanical device that can perform tasks and interact with its environment, without the aid of human interaction. 

Who was Isaac Asimov was an american author and teacher of biochemistry,he work for science friction and work for his popular science books.

What were the three laws of Isaac Asimov that states for the robots.
1.A robot may not injure a human being ,or through inaction,allow a human being to come harm.
2.A robot must obey orders given to it by human beings except where such orders would conflict with the first law.
3.A robot must protect its own existence, as long as such protection does not conflict with the First or Second Law.
4.The fourth law is consider the Zeroth Law.A robot may not harm humanity,or,by inaction,allow humanity to come to harm.

Meaning of each law;
1.A tool must not be unsafe to use.
2.A tool must perform its function efficiently unless this would harm the user.
3.A tool must remain intact during its use unless its destruction is required for its use or for safety.

What happens if the robots brake this rules;
they could rule the world and its very damage to us.They just care about themselves they are selfish.
Well not all the robots follow this 4 rules so it means that the world will end in one day at any moment,because this rules is make to control the robots.

How to draw an angle bisector

Step 1: Locate the original diagram of the angle.
Step 2 :   Locate the  vertex of the angle.
Step 3 :  Place the tip of the compass on the vertex of the angle and draw an arc which cuts each arm of the angle at two different points. 
Step 4 :  Place the tip of the compass on one of the points where the first arc cuts an arm of the angle.
Step 5 : Place the compass' tip on the point of intersection of the first arc and the other arm, without changing the width of the compass. 
Step 6 : Draw a line connecting the vertex of the angle and the point of intersection of the second and the third arcs.

How to convert from a fraction to a decimal

Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s.
Step 2: Multiply both top and bottom by that number.
Step 3. Then write down just the top number, putting the decimal point in the correct spot .

How to convert from a decimal to a fraction

Step 1: Write down the decimal divided by 1, like this: decimal/1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
Step 3: Simplify  the fraction
