1. How to calculate how much time is left before sunset.

This trick is a very easy one to learn. With your fingers touching, put your left hand up to the sky with your palm facing you. Then, place it so that the bottom of the sun touches the top of your index finger. Finally, count the number of fingers it takes to touch the horizon.

Each finger is classed as 15 minutes, so if you have four fingers between the sun and the horizon it means there are 60 minutes left before the sun sets. Three fingers mean there are 45 minutes left, and so on…

2. How to tell the number of days in each month.

This is so simple and it will stop you from ever asking how many days are in each month. Make a fist using both your hands, then start counting the months using your knuckles and the spaces in between them.

If a month lands on a knuckle, it has 31 days. If it lands in the space between, it has 30 or less, like it’s the case with February.

3. How to tell if the moon is waxing or waning.

The one is also very simple. You just need to remember these three: O, D and C. Obviously, if the moon looks like an O, it’s a full moon. If it looks like a C it is waning, and if it looks like a D, it is waxing.

4. How to remember the Roman numerals.

This is by far the best way to remember Roman numerals, remember the following phrase: My Dear Cat Loves Xtra Vitamins Intensely.

The first letter of each word in the phrase represents the Roman numerals going in descending order. So, M is 1000, D is 500, C is 100, L is 50, X is 10, V is 5 and I is or course Image result for roman numerals rhyme

5. How to check if a battery is still useful.

This one is extremely practical. Simply lift your battery a few centimetres above a table and let it drop. If the battery bounces and falls, it is empty. If does the exact opposite, it means it is full!

6. How to multiply 6, 7, 8 and 9 using your fingers.

Turn both your hands so that your palms are facing you. Assign each finger a number and start with your pinkie. Pinkies represent 6, ring fingers represent 7, middle fingers represent 8, and your indexes are 9s. Your thumb is 10s.

7. How to multiply the number 9 using your fingers.

If you ever need to multiply a small number by 9, the method is even easier. Firstly, put both of your hands up, with your fingers outstretched. The left pinky represents the number 1, the left ring finger represents the number 2. The left middle finger represents the number 3, and so on all the way to 10.

Now, let’s say that you want to multiply 9 by 3. You need to bend the third finger downwards. Then, count the fingers to the left and the right of the bent finger. In this case, we have 2 on the left and 7 on the right. Next, just put the numbers together, and you get the answer, which is obviously 27.

8. How to quickly measure the degrees of an angle.

You can do this using only one hand. First, spread your fingers as much as possible. Next, put your palm down onto the angle you wish to measure, with the pinky finger touching the bottom side. Your pinks always represents 0°.

Now, just see which finger the angle comes closest too. The angle between the thumb and pinky finger is 90°, between pinky and index, is 60°, between pinky and middle, is 45°, and between pinky and ring is 30°.

9. How to quickly measure distance.
