How to Calculate Quickly in Your Head

How do those seemingly mental math geniuses do it? Are their brains really programmed differently, allowing them to do what seems to be mental magic? What gives here? Maybe they have integrated circuits instead of dendrites?

The truth is, they more than likely know a number (excuse the bad pun) of math tricks that allow them to quickly find answers to math certain operations. There are many short cuts that can be employed for math problems involving addition, subtraction, multiplication, and division. If you spend some time rehearsing these methods, then you too can perform these seemingly miraculous feats.

For instance, suppose you wanted to multiple 43 x 11. Well, you may be able to solve this problem in your head already if you realize that you can first multiply 43 by 10, and then adding 43 to the result. Sure enough, the answer is 473. This works relatively quickly, but there is another method that you can use to get the answer more quickly!

This is a special case for multiplying two-digit numbers by 11. Indeed, the method can be used more generally on larger digit-numbers, but let’s look at how to employ this method with two-digit numbers:

First, take the digits in the number you are multiplying by 11, and add them. In our case (43), it is 4 + 3 = 7. Now take the result, and place in between the two-digit number. In our case, take the “7” and place it between the “4” and “3”. Did you see the result? Right! it is the answer 473!

Pretty neat, huh? Keep in mind that other problems may involve carrying-over numbers, but with a little practice, this will become almost natural.

This was a special case for numbers multiplied by 11, but there are many other methods you can use to calculate more complex problems quickly in your head.

Happy calculating!

Left Handed Facts

It is developed in pregnancy, by ultrasound you can see which hand is licked or close to mouth most. While Most people are right handed, but 10% of the world is not. And also they are more common in males than females. That’s another fact about left handed people because they are frequently referred to as “lefties.” Another common nickname for them is “southpaw” (particularly in a sports context). This nickname occurred during the 1890s due to left handed baseball pitchers. Batters are facing east so that the afternoon sun does not shine in their eyes.

Do You Know?

* There seem to be a high likelihood that in twins, one will be left handed. It is believed that there may be some genetic link for left hand preference. There has not been a specific gene pinpointed that is the “left handed” gene as of yet, however it does seem like left handedness runs in families.

* Before birth, exposure to high testosterone may can lead to left handed child (because high rates of testosterone suppresses left hemisphere of the brain).

* 25% of astronauts are lefties.

* Every year Over 2500 people die from using tools which was created for ‘right handed’ people. Life can be difficult for lefties simply because everything is made for right handed individuals. Consider knives, for example, because they are mostly made for righties. The computer mouse is almost always on the right side of the computer and that makes it difficult for lefties to handle. Most guns and golf clubs are made for right handed people. Finding the other versions are easier today, but they can be more expensive.

* Another left handed fact is lefties sometimes find it difficult to complete their school work simply because most desks are made for right handed individuals. Those who are lefties have their arms hanging out in the air when they are trying to write, which makes it very difficult. Maybe it is because of this that many of them have poor handwriting.

The Dark Side of Higher Education

Investment banks has fallen, national banks have betrayed our trust, government actions in majority of countries around the world are being frowned upon by the people (examples include the Gaza war, the Wall street bailout which is a bailout for the rich while the main street suffers the burden) and you just don’t know who the heck to trust anymore. Since you can’t put you faith in Uncle Sam or whatever, you put your trust on institutions of higher education, universities, polytechnics and others. You figure that their vaulted names are what is dependable on and they can deliver you wisdom, excellence, success and a great livelihood. The rest of the world, banks, public schools, environment, corporations etc, may be going to hell but you trust that if you try hard enough, and pay enough, you’ll get your money’s worth at universities that promises so much.

As a result of this belief, you incur tens of thousands, even hundreds of thousands in student loans or loans from parents (if you have a heart, you will consider it as a loan) since it is too much a sum to pay off on your own. As what is shared with me by a senior member of a university, a student’s school fees is only a very small fraction of the amount that the university needs, with the rest coming from government(also not a very huge sum) and the private sector, foundations, companies and like (a very significant amount).

It’s just economics from here on. Times are bad. Universities are facing more and more competition, since there are many hungry wolves out there scraping for a piece of the slice of higher education industry that has a growth rate that is increasing every year. Since a significant of funds of universities come from the private sector, these institutions will not want to part with their highly paid directors who know how to develop relationships with highly generous alumni. They don’t want to scale down their astronomical building and expansion plans either. They certainly don’t want to lower tuition rates or housing or other fees.

The question now is this: Faced with more competition, more uncertainty about global outlook, more needs of funds (for the development of the infrastructure, the ever growing salary of professors and other stuff) and lesser donations from the private sector (again due to uncertainty and budget tightening), where are they going to “squeeze” the funds from?

The answer: Students. The interests of the students will be sacrificed because they are the least protected and most innocent of the whole academic community. There are numerous articles online that will support this. Sure, Yours Truly think that around 25% of them are too far from the truth, but the sheer amount of complaints, dis-satisfaction and other related articles are just too much to ignore. I don’t believe that all of these allegations are false, how can it be?

Don’t take my words at face value. I only aim to open up your mind. Do your own research online or elsewhere. Talk to people higher up in the education institutions who can be honest with you. You don’t need me to convince you, you need to convince yourself. Find out what is the state of the higher education industry right now, what wrongs are being committed against the very people who relied on them, the students.
