# Simple Tricks Of The Grandmother That Will Become A Living Encyclopedia!

Some of the tricks are so simple and useful that they can be used for many generations. But over time, they are somehow forgotten and transformed into what we usually say “My grandmother told me …”. We decided to remember some of the old tricks we learned while we were kids, and for some reason we forgot them.

**1. DETERMINE THE TIME BEFORE SUNSET**

Put your fingers together and stretch your hand so that the sun is on your index finger. Count the number of fingers to the horizon; each finger represents an approximate 15 minutes for the sunset.

**2. KNOW THE NUMBER OF DAYS OF EACH MONTH**

With the closed fist counts the months by the knuckles. Each knuckle and each cleft between them represents a month. If the month falls on knuckle has 31 days, if it falls into a cleft has 30 or less.

**3. CHECK THE QUALITY OF THE BATTERIES**

Raise the battery to one or two centimeters on a table and let it fall; if it staggers and falls it has no load.

**4. THE EASIEST WAY TO TELL WHETHER THE MOON IS WAXING OR WANING**

To know in which phase the moon compares it with the letters D, C, and O. Moon D is increasing, O is full Moon and C is waning.

**5. MEASURE ANYTHING WITH YOUR HANDS**

If you need to measure something, but you do not have a meter or a ruler, then you can do it with your fingers with one hand. According to human proportions, the distance between the edge of the thumb and forefinger is about 18 cm, and the distance between the thumb and the finger is about 20 cm. Of course, this method is not precise enough, because everyone has a different hand size. But it can be useful if you want to measure a large object.

**6. MULTIPLICATION IN FINGERS**

Usually, children quickly remember the multiplication of small numbers, but with numbers 6, 7, 8 and 9 there are difficulties. To help children, teach them a simple trick. Turn your palms toward you and assign to each finger of the left hand a number, from 1 to 5, starting with the little finger; and from 6 to 10 to each finger of the right hand starting with the thumb. Now, to multiply, for example, 9 × 7, lower the assigned finger with the number 7; the number of fingers remaining to the left of that finger will be tens, and the number of fingers to the right units. In the example, 9 × 7 = 63.

**7. THE ORDER OF THE PLANETS**

It is enough to remember the following phrase and use it as a mnemonic resource: “My Old Aunt Marta Never Knew Nothing to the Bread”; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
