Do you remember those **ancient digital calculators that we used at school or institute**? Although many do not have the best memories of mathematics or physics classes (in which we had to use them very often), we can give a new use to their liquid crystal screen with **a good handful of clever and funny tricks**. So much so, that by interpreting the numbers on the screen and with not so obvious mathematical calculations, we can do lots of **calculator games** to surprise our friends and family. We leave you with the **9 tricks calculator more witty** What you can do if you continue Our advice.

## math trick

- Mark the numbers 98765432 on your calculator and divide that figure by 8
- The result is 12345679, yes, the numbers in order, but the 8 is missing
- Multiply the missing number (8) by 9
- Now, we multiply the result (72) by the numbers in order above (12345679)
- And the result is…

## Seven will always be seven

- Have a friend of yours think of a three-digit number and mark it twice on the calculator, for example 789789. Tell him that the result will always be 7
- Divide the number by 11 and see the result
- Divide the result by 13 and see the result
- Divide the result by the three-digit number at the beginning
- And the result is always 7!

## The fertility trick or “THE BABY”

- A couple wants to have children, so let's get to work!
- They try it for 13 days with their 12 nights of the 356 days of the year (13x12x365), with the result of 56940
- 2101 euros are spent on clothes and diapers, a figure that we must subtract from the previous result (56940-2101), with a result of 54839
- The results came after 14 days (54839×14), with a result of 767746
- If we divide this figure between their 2 hearts in love, we obtain 383873
- Now, turn the calculator and interpret the number in letters: “THE BABY.”

## Reading numbers backwards

Can **write a multitude of words with numbers on our calculator, as long as we read backwards**. Thus, we can easily interpret the letters I, E, H, S, G, L, B, O, Z and D with the numbers 1, 3, 4, 5, 6, 7, 8, 0, 2 and 0, respectively. . With these numbers alone we can write more than 1,400 words. Use your imagination! We leave you with some examples:

- 15 to write “YES”
- 236 to write “FISH”
- 3838 to write “BABY”
- 376006 to write “GOOGLE”

## The game of greeting with your calculator

Do you want to surprise a friend or family member without saying anything? **Grab your calculator and dial the number 0.7734**. If you turn the calculator over, you will read HELLO. The decimal point is so that the calculator allows us to mark the 0 at the beginning of the figure and so that it does not disappear when reading backwards. On the other hand, if your calculator has the open-top 4 instead of the more common closed 4, you won't need to use the decimal, since the open-top 4 is already read as H.

## love above all

Are you a very loving person? Do you want to show your affection to others without saying a word? **Enter the figure 50538 and turn your calculator** in front of the recipient.

## Study just in case!

A 10-year-old girl who always got a 10 on exams, one day she got a 7 and her father and mother took her **50535**. Read the number backwards!

## observing space

1 galaxy, 9 planets and 695 stars. What star is in the center of the galaxy? (1+9+695) = **SUN**

## Your lucky number

- Write the number 98765432
- Divide that number by 8
- The result is the same number backwards but without the 8
- Choose your favorite one-digit number and multiply it by 9 mentally
- Now multiply the result by the number shown on the screen
- All the figures in the result will be our lucky number

## Extra trick: Addition races!

Do you consider yourself **the fastest typing on your calculator**? Now you can challenge your friends and check it out with stopwatch in hand. For this only **we must dial 1 and the + key**. Now comes the time to **press the = key to add one at a time for one minute**, as fast as possible. Who will reach the highest number?
