Using Mathematics in the Real World

When will I ever apply this in my life? This question has echoed through the halls of mathematics classrooms in many places. Struggling students become frustrated with some complex math problems and they give in to the idea that they will never employ mathematics in “real life” situations. However, math helps solve various work-related or real world problems.

First, math helps us to build things. Ask any construction worker or contractor and they will tell you that math is very important when it comes to creating anything. Building something that adds value and last requires the right set of tools, creativity, and mathematics. Armed with math, you have the ability to check the project estimates and, therefore, ensure you’re getting the best value.

Second, mathematics makes traveling easy and fun. When traveling, mathematics shows up in various ways: estimating the amount of fuel that a car needs. Calculating fuel usage is important for long distance travel. Failing to calculate will see you stranded on the road and taking much longer than expected. In addition, you may use mathematics throughout the journey by counting exit numbers, paying for tolls, checking tire pressure, etc.

Math also helps people to save money. Many experts agree that individuals who do not have strong math skills tend to spend, save, or invest money based on their emotions. Students who grasp math concepts properly save and spend their money without frustration or fear.


How to Maintain Hard Drive/ Software of a Computer

A well-maintained computer provides substantially higher speeds, regardless of hardware configuration and setup. Although all systems degrade over time, there are several tips on how to delay the inevitability.

All the junk that are left by browsers should be cleared. To do that, use the Disk Cleanup utility that comes with the Windows systems. You can also download a freeware program like CCleaner to do that for you. Bleachbit and Kleansweep can be used in Linux. Cache and cookies left behind by a browser can amount to many gigabytes of wasted space. Therefore, it is important to delete them.

Destroy viruses and/or spyware on your computer. There are many tools available to do that. Kaspersky and AVG Anti-Virus are examples of such tools. is one of the best places to legally get these tools.

Each month, defragment the hard drive to keep the computer running well. Windows XP has a utility to do that, but a tool known as Magical Defrag can help you to automatically defragment your systems during inactivity periods.

Delete videos you no longer watch and uninstall programs that you don’t use. A computer with more free space has a high processing speed.

Use computers disk management systems. For Mac, look for the Applications Folder, choose Utilities Folder and launch Disk Utility. For Windows, choose Performance and Maintenance and select “Rearrange items on your hard disk. Then select “Free up space on your hard disk.”


4 Things to Do With a Mathematics Degree

Study of mathematics in the university provides a gateway for you to land in the most prestigious careers. Careers requiring a degree in mathematics are quite numerous and include the following:

Careers in finance and accounting.

Many finance and accountancy careers require one to be a mathematics degree holder. The beauty about this career is that it covers all areas of every industry. In order for you to gain a competitive advantage in the employment market over others, doing a short finance and accounting professional course will be necessary.

Careers in banking

Career opportunities in banking can easily make you be spoilt for choice. This is due to the fact that these careers are quite numerous. For some jobs you will need to do banking or finance professional courses to qualify.

Actuarial careers

Actuarial careers involve being an actuary. An actuary is tasked with the role of evaluation of financial risk so as to provide informed advice to clients. It is important to note that working at high-risk financial area attract the most handsome remunerations as compared to low-risk areas.

Careers in statistics

Mathematics skills are also relevant in a field of statistics. Statistics exist in many industries: healthcare, communication, transport. A statistician’s job is mainly to collect, analyze, interpret and present data. A short course in IT will put you ahead of others in this field.


Differences Between Digital and Analog Computers

Due to digital computing limitations in the 1960s and 1970s, technicians, scientists and engineers used analog computers to solve complex problems. After advancement in digital technology, analog computing died in 20th century. Although both digital and analog solve similar problems, they have some differences.

In digital computing, numbers are produced as output. They use printers, disc drives, display screens and other peripherals to capture output. On the other hand, analog computers generate voltage signals as outputs, and have sets of oscilloscopes and meters to display the voltages.

Another major difference between digital and analog computers involve electronic circuits. Analog computers circuits use signal generators, op amps, and network of capacitors and resistors. These circuits continuously process voltage signal. On the other hand, digital computers use various on-off switching circuits, such as clock pulse generators, microprocessors, and logic gates.

Although you can program both digital and analog computers, the methods of programing are different. To program an analog computer, one is required to electrically connect different sub-systems with patch cables. Digital computers use well written lists of complex instructions, including moving data from one place to another, comparing two numbers or multiplying two numbers together.


Classification of Micro Computers

A microcomputer is a small and relatively inexpensive computer that has a microprocessor as its central processing unit. It includes memory, a microprocessor, and minimal input/output circuitry built on a single printed circuit board.  Micro-computers are classified into workstations, personal computers, laptop computers and Mini PCs.

  1. Workstations

Also known as desktop machines, workstations are mostly used for intensive graphical applications. Compared with personal computers, they have more processor speed. They use sophisticated display screens that feature high-resolution colour graphics.

  1. Personal Computers

Also called PCs or home computers, the personal computers are very popular computer systems. They are more affordable and easier to use than workstations. They are self-sufficient computers intended for one user. Most often used for database applications and word processing.

  1. Laptop Computer

Laptop Computer or notebook computers are portable computers that are mainly carried in a briefcase.  They are wonderfully functional and portable, and popular with travellers who require a computer every place they visit.

  1. Mini PC

Mini PCs are tiny computers that can fit in the palm of your hand. An example of Mini PC is pen-based computers that use a pen-like stylus. Special hardware design techniques make them smaller, portable and light weight computers.
