FX-991 ES PLUS is the most widely used calculator today. It is used by students, engineers, educators, business mans and other professionals. This calculator has 580 functions, and one of this function is the conversion factors, which is very important to remember. During Board Exams the back cover of the calculator is taken away, in which conversion factors are found. So, you need to memorize the number keys with corresponding conversion values to use your calculator in different ways.

As part of this community, I will share with you my technique on memorizing this numbers keys. Seat back and let’s expand your creativity.

The Conversion Factors

FX-991 ES PLUS calculator has 40 unit conversion number keys, so, we will group these according to their classification: mass, velocity, area, pressure, volume, power, length, energy and temperature.

The Memory System

On this technique, we will use three major system; the body; the number and the linking thoughts. We are going to place the nine (9) conversion classifications on your body beginning from feet to head.

Use your imagination. Create mind movies while putting this information into your body. The more you bring information to life, the more it will be remembered and remains in your long-term memory. Used the SEE Principle: use your senses, exaggerate with humor, trick your mind, have fun and give your pictures actions.

1. MASS
   Let's put the Mass on the feet. We know that when a person is standing, the feet received the weight, so imagine yourself standing on giant feet.

2. VELOCITY
   Put Velocity on the knees. Imagine yourself running, and the most of your body exerts the movement is your knees, or you can imagine knees without body running after you.

3. AREA
   Put the area on the legs. The largest bone ‘’ femur ‘’ is found on the legs, so the word '‘largest'’ relates to the word ''area''.

4. PRESSURE
   The part of the body that releases pressure is no other than butt so put the word pressure on the butt.

5. VOLUME
   When we eat, the storage tank of our food is our stomach, so ''storage tank'' relates to the word ''volume''; the volume of food in the stomach.

6. POWER
   Put the word power on the palm. When we pray, we put our palms together, so remember; prayer is the most powerful words.

7. LENGTH
   When we stretched our arms sideward, it's equivalent to one meter, so, put the length on your arms.

8. TEMPERATURE
   When a person is sick, we commonly put the thermometer on the neck, so ''thermometer'' relates to the word ''temperature''.

9. ENERGY
   Put the word energy on the head. Imagine yourself sending energy to the universe to attract the law of attraction.

Translate Numbers into Words

Each conversion classification has a corresponding number keys. We need to connect this numbers keys to each classification by translating numbers into words.

Example:

For MASS:

Based on the groupings found in conversion classification table.
It falls on 21 – 24 and 33 – 34.

Note: Use the table guide above to know the value of numbers in letters.

N represents for number 2
D represents for number 1
R represents for number 4
M represents for number 3

From the above number letter representation, we can sum up consonants; for 21 – 24 we can get NDNR; for 33 – 34 we can get NDNR and MMMR. To translate this letters to words, we will insert vowels, but remember that vowels and the word ‘’why’’ has no value in memory numbers system. So, we can create the words NoDoNoR and MaMaMeRy – sounds like ‘’No Donor’’ and ‘’Mama (mother) named Mery’’.

Do it again using the remaining conversion classifications, but for now, let’s assume that we already translated the numbers into words. Look below and examine their transcription.

For VELOCITY:

19 - 20
Creates a word DeePNeeS – sounds like ‘’deep knees’’.

For AREA:

11 - 12
Creates a word DeaDToNe – sounds like ‘’dead tone’’.

For PRESSURE:

25 – 28
31 – 32
35 – 36
Creates a word NeiLNoF MeeTMeN in MoLiMiSH – seems like ‘’A man named Neilnof meet men in Molimish’’, assuming that ‘’Molimish’’ is a place.

For VOLUME:

13 - 16
Create a word TeaMDiSH – sounds like a ‘’team of dish’’.

For POWER:

29 - 30
Creates a word NoBeMS – sounds like ‘’novenas’’.

For LENGTH:

1 – 10
17 – 18
Creates a word DoTS and DoKDaVe – sounds like ‘’dots’’ and ‘’Doctor Dave’’.

For TEMPERATURE:

37 - 38
Creates a word MaKeMoVe – sounds like ‘’make a move’’.

For ENERGY:

39 - 40
Creates a word MoBRiSe – sounds like ‘’move and rise’’.

Here is a full image of the combined memory system.
