People barely remember the things they learned at school, mostly because they think that they’ll never use them. However, the tricks they learn come pretty handy later in life.
Some tricks can always be used, regardless of the generation or the presence of technology. Here’s a list of tricks you can use every single day of your life, without looking at your phone.
How long before the sun sets
Place your hand straight in front of the sun and keep your fingers together. Make sure your index finger is on the sun.
All you have to is count how many fingers there are to the horizon line. Every finger equals about 15 minutes – and now you will always know how much time is left until sunset.
Know the number of days in a month
This is probably one of the oldest tricks in the book. Close one of your hands and form a fist. Next, count the knuckles as the months in a year – as shown on the image below.
You can also form fists with both of your hands and as you end counting on one fist, you can continue counting on the other. Knuckles are months that have 31 days in them, and the dip between the knuckles are months with 30 days or less (that goes for February).
Can you tell what phase the moon is in?
This is a trick most children know – the shape of the moon tells you what phase it’s in. All you have to do is use letters of the alphabet.
For example, ‘O’ represents a full moon, the first quarter of the moon looks like a ‘D’ and the third and last phase looks like a ‘C’.
An Easy Memory Trick
Most people don’t really know how to use Roman number properly, but there’s an easy way to learn and remember them.
If you remember the phrase above, you’ll know that the first letter of each word in the phrase is a Roman number. Now you just have to remember what number each letter is and they’re written in a descending order.
Multiply using fingers
We all learned multiplication as children, and to be honest, the first ten tables were rather easy to learn. However, the troubles begin when you move to double digits. Believe it or not, some people have problems with 6 and above. But there’s a trick…
Face the top of your hands towards your face and imagine that every finger is a number (1-10). Number 1 should always be the pinky on your left hand (as shown below). If you want to multiply 7 x 8, join the number 7 with the left hand with finger number 8. Count with the connected fingers towards the bottom. The answer should be 56.
The same goes for multiplying with 9. The image above displays the simplicity of multiplying with your fingers.
This is by far the easiest way of measuring short distances. If you don’t have a measuring instrument near you, just use your fingers. Of course, you need to keep in mind that every human measures in accordance with their own size.
The distance between the tips of your thumb and forefinger should be about 18 centimeters (7 inches).
This will allow you to get an estimate of the space between things, not an accurate measure. However, you can measure the distance between your thumb and pinky (or thumb and forefinger) once, and you will always have a ruler with you.
Know the degrees of an angle
The majority of people doesn’t know what shape forms what angle. The simplest way to learn is to place your palm on the surface you want to measure. Your little finger should lie flat at the bottom and that is your zero degrees angle.
The angle between your thumb and the little finger should be 90 degrees and the rest is displayed on the image above. Quite simple when you think about it.
