Some everyday tricks are so useful and simple they can come in handy to more than one generation.

Yet over time, they’re somehow forgotten, and they turn into what’s called “grandma’s tips.”

Some everyday tricks are so useful and well known at one generation, but over time, they’re somehow forgotten and people start calling them traditional or old-school tips.

Below are 7 tricks from childhood learnt from school, but still can be used today.

 

#1.point 79 | The Degrees Of An Angle Using Hand

point 107 |

Spread your fingers as much as possible, and put your palm on a surface over the angle of which you want to measure.point 324 |

The pinky finger should lie on the bottom side and it means 0°.point 56 | The angle between the thumb and the pinky finger will be 90°, the angles between the pinky finger and the other fingers are, respectively, 30°, 45°, and 60°.point 194 | 1

 

#2, Length Using Hand

point 18 |

If you need to roughly know the measurement of an object without a ruler, you can use your fingers of one hand.point 225 |

In accordance with the average human proportions, the distance between the tips of the thumb and forefinger is about 18 cm (7″), and the distance between the thumb and the pinky finger is about 20 cm (7.point 181 | 87″).point 188 | 1

Of course, this method isn’t absolutely accurate because each person has a different hand size. Yet it can be useful if you need to measure a large object with a small ruler, just measure the distance between your fingers in advance and use your hand to measure the object.

 

#3. Doing Multiplication On Fingers

Children can quickly remember doing multiplication of small numbers, but they have difficulties with the numbers 6, 7, 8, and 9. To help your child with this, teach them this simple trick.

Turn your palms to your face.point 26 | Number each finger, starting with the pinky finger, from 6 to 10.point 84 | Now, for example, to multiply 7 by 8, connect finger #7 on the left hand with finger #8 on the right.point 175 | The number of fingers at the bottom, counting along with the connected ones, means tens (we got 5 of them).point 273 |

As for the fingers located at the top, you need to multiply them among themselves, they mean units (in our case, multiply 3 by 2).point 118 | Answer: 7×8 = 56.point 133 | In this way, you can quickly multiply by 6, 7, and 8.point 179 | 1

 

point 185 |

To multiply by 9, straighten your fingers, and put your hands on a table with your palms down.point 381 |

Now, to multiply any number by 9, just bend the corresponding finger.point 62 |  Fingers “before“ mean tens, ”after“ means units.point 114 |  For example, to multiply 7 by 9, bend the 7th finger.point 165 | 6 fingers remain “before” and 3 ”after.point 208 |

” We get the answer: 7×9 = 63.point 32 | 1

 

#4. Checking The Quality Of Battery

It’s very simple to differentiate a good battery from a bad one. Raise two batteries 1-2 cm above a table, and drop them. The battery that bounces and falls is empty.

 

#5. Knowing If The Moon Is Waxing Or Waning

To determine the moon phase, use the shape of the alphabet letters D, O, and C. A full moon is in shape of O, the first quarter is in shape of D, and the third is in shape of C.

 

#6.point 9 | Knowing The Number Of Days In A Month

point 39 |

Make a fist, and start counting the months by each knuckle.point 201 |

 Each knuckle bump and gap is a separate month.point 44 |  If you count on one hand and you reach the end, start again with the knuckles of the same finger you ended on.point 140 |  If the month is on the knuckle bump it means there are 31 days.point 200 | If it’s on the gap it means there are 30 or less days.point 250 | 1

 

#7. Determining The Time Left Before Sunset

Keep your fingers together, and reach out your hand so that the sun right above your index finger. Now count the number of fingers to the horizon line. Each of the fingers represents approximately 15 minutes until sunset.
