looping and lines!




We learnt how to repeat coding and go to new lines

For h/w I multiplied two numbers together many times



In class, we divided numbers and also divided numbers with remainders!











Robots

Why are they useful??
  • Robots produce more accurate and high quality work.
  • They can produce a greater quantity in a short amount of time.
  • They can work at a constant speed with no breaks
  • They can work in dangerous conditions,

What are the potential problems??
  • Robots have a high cost of for both the production and the purchasing.
  • It needs maintenance to keep it running
  • People can lose jobs in factories
  •  It needs a supply of power                                          
In my opinion, I think people show be aware of the dangers that robots can cause and I think the society show be worried too.  Even though they are a very clever and impressing piece of technology, I think the disadvantages are much more important.  The disadvantages are not to be overlooked!

First of all, I agree that computers are only as smart as their programmer.  This is because computers need assistance and cant program by themselves.  I think it would be impossible for a computer to learn how to learn by itself, because I feel that they can only learn by the person who is controlling them.  Lastly, I do think programmers need to be careful with creating robots who mimic human intelligence because they can get out of control.

Performing in calculations,counting in binary and the fibonacci sequence

1) What is the formula used to return a whole number when doing division?
   =a\b (a divided by b) (e.g. 5//2=2)

2) What is the formula used to return the remainder when doing a division? How does it work? Explain with an example.
a%b

3)Why is it important in computing to understand number systems and in particular binary?
It is important to understand number systems because in many jobs, people are expected to use their knowledge of number systems and codes to work.  Binary is important because it is a way to process the data.

4)How does binary work? i.e how do we convert a number from decimal into binary?
The value of any digit always depends on its position in the whole number.  To convert from decimal to binary, or the other way around, you need only look at the figures place in the whole number and add up its value.
