Answer:
Cogs and Calculators
It is a measure of the brilliance of the abacus, invented in the Middle East circa 500 BC, that it remained the fastest form of calculator until the middle of the 17th century. Then, in 1642, aged only 18, French scientist and philosopher Blaise Pascal (1623–1666) invented the first practical mechanical calculator, the Pascaline, to help his tax-collector father do his sums. The machine had a series of interlocking cogs (gear wheels with teeth around their outer edges) that could add and subtract decimal numbers. Several decades later, in 1671, German mathematician and philosopher Gottfried Wilhelm Leibniz (1646–1716) came up with a similar but more advanced machine. Instead of using cogs, it had a "stepped drum" (a cylinder with teeth of increasing length around its edge), an innovation that survived in mechanical calculators for 300 hundred years. The Leibniz machine could do much more than Pascal's: as well as adding and subtracting, it could multiply, divide, and work out square roots. Another pioneering feature was the first memory store or "register."
Apart from developing one of the world's earliest mechanical calculators, Leibniz is remembered for another important contribution to computing: he was the man who invented binary code, a way of representing any decimal number using only the two digits zero and one. Although Leibniz made no use of binary in his own calculator, it set others thinking. In 1854, a little over a century after Leibniz had died, Englishman George Boole (1815–1864) used the idea to invent a new branch of mathematics called Boolean algebra. [1] In modern computers, binary code and Boolean algebra allow computers to make simple decisions by comparing long strings of zeros and ones. But, in the 19th century, these ideas were still far ahead of their time. It would take another 50–100 years for mathematicians and computer scientists to figure out how to use them (find out more in our articles about calculators and logic gates).

Answer:
try putting "uk-" or "us-" depending on where you are, you could also go through your settings and try to allow everything.
Answer:
Some schools have the option to block only on regular tabs, try going into settings and disabling the block to go on incognito tabs.
Another option would be to use a different web browser, something less known but good enough that it works and isnt blocked.
You can also find certain things on online where it tells you what websites to go to, then copy a link and paste it down into the search bar where the page will come up unblocked.

What are the advantages and disadvantages of top-down and bottom-up programming? How would you decide which one to use? Do you approach problems in your real life from a bottom-up or top-down approach?
Answer:
Question: What are the advantages and disadvantages of top-down and bottom-up programming?
Answer:
Top-down programming is a process of writing programming codes that contain specific instructions for a computer to carry out the instructed task. Usually, Top-down programming comes as software that enables the division of problems that are initially complex into simpler parts. An example is a kind of software developed to give loans to worthy clients. The software may be broken down further to check the bank statements of the client, calculate the earning and spending capacity of the client, Amount paid on utilities.
Advantages of Top-down programming:
1. Top-down programming makes teamwork possible as a system is divided into sub-systems which individuals can handle separately before merging the sub-systems together.
2. Checks and testing become easy.
Disadvantages of Top-down programming:
1. Breaking systems into parts may be time-consuming as there is a need for more planning before working on individual sub-systems.
2. Error could be possible.
Bottom-up programming is a software of a method of design which is opposite to what the top-down programming does as the bottom-up programming works on the sub-systems first and then combine later into a bigger system. This makes use of the existing resources with the aim of generating a bigger result.
Advantages of Bottom-up programming:
1. Adaptability - Bottom-up programming makes adaptability easier.
2. When used in a company it gives all workers the room to make a contribution towards achieving bigger results, improving operations generally.
3. It makes one start a bigger project with the available resources.
Disadvantages of Bottom-up programming:
1. Result could be affected as some workers lack the needed experience to execute some tasks successfully.
2. Lack of desired unity among workers with differences in objectives resulting to endangering the result.
Question: How would you decide which one to use?
Answer:
It depends on the picture of how the result would look like, the goal of the organization employing it, the skill-set among workers available to do the task, the nature of the task. If a larger goal is to be achieved, smaller sub-systems could be used and joined at the end to get a system meaning bottom-up programming would be used. In cases for instance where output is to be determined for instance staff salaries, the output would be broken into simpler units to allow solutions for separate units then we could use top-down programming.
Question: Do you approach problems in your real life from a bottom-up or top-down approach?
Answer:
I approach problems from a top-down approach because it allows checks and testing easy, and the act of breaking systems into sub-systems makes it easy for me to approach each sub-system with a result-oriented plan.
Answer:
Some advantages of top-down are that you can start off from what you know and figure out what you need to complete it, the advantage to bottom-up is that you can make something new . if you are starting something from scratch and you don't know what the end goal might be you would use bottom-up but if you already have an idea or the final product of what you want you would go with the top-down approach.
Hope this helpedHave a great day!
