FUNNY CALCULATOR TRICK

1. take a calculator
2. type in "12345679" (remember not 8)
3. times it by any number multiplied by 9,
lets say if u you want 5as answer , 5*9=45, so 12345679*45=?

try multiplying by: 9,18,27,36 and so on...


& see the magic of maths

TO FIND SQUARE OF 3-DIGIT NUMBER

LET THE NUMBER BE ABC

SQ (ABC) is calculated like this

STEP 1. Last digit = last digit of SQ(C)
STEP 2. Second Last Digit = 2*B*C + any carryover from STEP 1.
STEP 3. Third Last Digit 2*A*C+ Sq(B) + any carryover from STEP
2.
STEP 4. Fourth last digit is 2*A*B + any carryover from STEP 3.
STEP 5 . In the beginning of result will be Sq(A) + any carryover
from Step 4.


EXAMPLE :

SQ (431)

STEP 1. Last digit = last digit of SQ(1) =1
STEP 2. Second Last Digit = 2*3*1 + any carryover from STEP
1.= 6
STEP 3. Third Last Digit 2*4*1+ Sq(3) + any carryover from STEP
2.= 2*4*1 +9= 17. so 7 and 1 carryover
STEP 4. Fourth last digit is 2*4*3 + any carryover (which is 1) . =
24+1=25. So 5 and carry over 2.
STEP 5 . In the beginning of result will be Sq(4) + any carryover
from Step 4. So 16+2 =18.

So the result will be 185761.

SHORT CUT TO MULTIPLY ANY NO BY 12

EG: IF WE WANT TO PERFORM

12 X 6

The first thing is to always multiply the 1 of the twelve by the
number we are multiplying by, in this case 6. So 1 X 6 = 6.

Multiply this 6 by 10 giving 60.

Now multiply the 6 by the 2 of twelve giving 12. Add this to 60 giving 72.

Therefore 6 X 12 = 72
