how to learn maths formulae

(1)  Spelling of Arithmetic:
A Rat In The House May Eat The Ice-Cream.

(2)  Dividing One Fraction With Another
Keep the first fraction, Change the sign from divide to multiply, Flip the last fraction.

Kangaroo Chewing Frog

(3)Greater Than or Less Than?

In Ramayana Shri Ram is greater than Ravan and Ram’s weapon is aero, open towards himself (greater one) with narrow point towards Ravan(smaller than Ram).

       (4)Metric Units of Measure in Order

* Kilo
* Hecto
* Deca
* Units [meter, liter, gram] M
* Deci
* Centi
* Milli

       Kahan Hai Dilli Mein DCM

(5)Mode & Median

(a)Mode
The mode is the value which comes Most of the times in a given series  “MOde” and “MOst” have the same starting 2 letters.

      The mode is the Most Occuring Data Entity.

       (b)Median
      The median sounds like Medium which also means middle so it splits the data

      down the middle, like the median strip in a road.

       (6)Which is the Numerator, which is the Denominator?

        Naughty Dada ji (N comes before D)

 (7)Multiplying Signed Numbers

From friendship:
friend = positive , enemy = negative
My friend's friend is my friend     (+  ×   +  =  +)
My friend's enemy is my enemy  (+  ×   -   =  -)
My enemy's friend is my enemy  (-   ×   +  =  -)
My enemy's enemy is my friend  (-   ×   -   = +)

       (8)Roman numerals

Roman Numerals: I =1, V = 5, X = 10, L = 50 , C = 100 , D = 500 and M = 1000.

or

Roman numerals: L = 50 , C = 100 , D = 500 and M = 1000. (LCDM)
Lallu Can't Draw Monkey.

Lucky Cows Drink Milk

         (9)Speed, Distance and Time

Remember the formula triangle

D = distance travelled                            
S = Average speed
T = Time taken

You can use the formula triangle in the following way:
If you need to find D, cover up D in the triangle and you get S × T

If you need to find S, cover up S in the triangle and you get  D / T

If you need to find T, cover up T in the triangle and you get  D / S

Or

Distance = rate × time
D = RxT
remember it as DiRT

(10)In Trigonometry we have: Sin=P/H, Cos = B/H, Tan =P/B

Where P = Perpendicular, B = Base , H = Hypotenuse

Some People Have Curly Black Hair Through Proper Brushing

Or

Sine = Opposite ÷ Hypotenuse

Cosine = Adjacent ÷ Hypotenuse

Tangent = Opposite ÷ Adjacent

You can use it in this way aswell, OHSAHCOAT (pronounced oh-sah-coat). It is interpreted as OHS-AHC-OAT

(11)Simple Interest Formula

Interest = principle × rate × time
 I = prt
Learn it as “I am PReTty ”

(12)Value Of Pi (π) 
Count the number of letters in each word:

Pi (π) to 12 decimal places: (Word lengths are digits)
See, I have a rhyme assisting my feeble brain, its tasks oft-times resisting.
3.141592653589

Pi (π) to 30 decimal places: (Word lengths are digits)
Now I, even I, would celebrate
In rhymes unapt, the great
Immortal Syracusan, rivaled nevermore,
Who in his wondrous lore,
Passed on before,
Left men his guidance
How to circles mensurate.

Or it is better to learn this by the help of numpic coding

(13) (a)Area Of A Circle 

d (diameter), r(radius)
Apple Pie (Pastry) are Square in shape: A = π × r² 

or

Apple Pie are Round & Red: A = π × r × r

(b)Circumference of a Circle.
Around the circle(Circumference) a Pie is running to save itself from a Dog: C = π×d

Or

Around the circle(Circumference) a 2 Pie are running to save itselves from an ugly Rat: C = 2π×r

(14) Division with 0 is not possible

We couldn't divide by zero because if we put the eggs in the bottom of the grocery bag they would break. It was okay to have the eggs on top.

(15)Feet in a Mile

5280 feet = 1 mile
5 Tomatoes
5 to (m)ate oe(s)
5    2    8   0 -- or 5,280 feet in a mile

For straight memorization, you can write everything(all the formulas) in one big column on a single sheet of paper, and go through the list over and over. To test yourself, you can try to remember the items on the list without looking on the sheet.

In the actual test itself, if you would have any trouble remembering something that you know you had written down in your notes or used in studying, you can visualize the page in your mind to try remember it.

you can see its structure aswell

A big bank hall1 is being cut by coal to open Mc Kaliya2 in the other part of it. On the opening Shiela Dixit is chief guest. Its cook's name is Andha Ganesh3 and he cooked a special dish for this occasion named as Zebra khad. First customer Lalu ji4 becomes the victim of a ghatna.

FREE MEMORY TECHNIQUE 1: Learn how to remember a list of ten Rivers 

By the end of this exercise you will be able to remember the following list of ten Rivers:

Severn, Thames, Trent, Aire, Ouse, Wye, Tay, Nene, Clyde, Spey 

Let's get started. Read through the following story and try to imagine it actually happening to you in your mind.

IMAGINE...

It's your seventh birthday. You're wearing a shiny badge with the number seven on it. Suddenly, teams of sports stars gatecrash the party: football teams, cricket teams, rugby teams - there are teams everywhere. You're terrified and need somewhere to hide. Where do you go? You dig a trench, and lie in it - covered by a pile of trench coats. Unfortunately there are so many coats on top of you that you start struggling for air. You're suffocating. All you can think about is air. You struggle to get out from amongst the clothes, but as you emerge you realise that you've accidentally stripped off some of the clothes you were wearing. Now you're standing there in just shoes and a pair of old Y-fronts! Someone hands you a large tray which you stand behind to hide your modesty - until you hear a loud voice shouting 'Nein! Nein!' You see a German man running towards you, horrified that you have his tray. To escape from him you stand on the tray and glide and slide across the floor, getting faster and faster until you take off and blast into outer space.

It's a crazy story, but read it through again and notice how it contains clues to a list of ten rivers:

Severn, Thames, Trent, Aire, Ouse, Wye, Tay, Nene, Clyde, Spey 

This story lets you remember the UK's ten longest rivers in exactly the right order. It includes striking image 'clues' to each word, connected into a chain of events that your brain will remember if you relax and let it happen.

Here are the clues:

- You're seven: SEVERN
- Suddenly you're surrounded by teams: THAMES
- You're hiding in a trench under trench coats: TRENT
- You're gasping for air: AIRE
- You emerge dressed only in shoes: OUSE
- ...and Y-fronts: WYE
- You hide behind a tray: TAY
- A German is angry and shouts 'Nein!': NENE
- To escape you slide and glide: CLYDE
- ...into space: SPEY
All learning can be as efficient and stimulating and powerful as this


FREE TECHNIQUE 2: Remembering a ten digit number 

By the end of this exercise you will be able to remember the following ten digit number in sequence:

1007120152 

Let's get started. Read through the following story and picture it in your mind.

PICTURE THIS ...



You're watching the television news. The door of Number Ten Downing Street opens up and out steps 007, James Bond. He's holding a large calendar: as the camera zooms in on it you can see that the first day of the month in the top left corner is highlighted. Suddenly, from that square on the calendar, playing cards start pouring out onto the street, all fifty-two of them

It's a strange story, but it has a purpose. It's designed to teach you this ten digit number:

1007120152 

Think back through the story. Each moment of it reminds you of a pair of numbers. It starts at Number Ten Downing Street (10). James Bond walks out (shorten his code to 07), holding a calendar of 12 months, on which the first day (01) is highlighted. 52 playing cards spill out... completing the sequence: 1007120152.

I bet you can even recall the digits in reverse order!

So why isn't everything as easy to remember? The answer is: it can be, if you know the secrets.
