The beauty of Math

1) age calculation :
remember u c tis at d net before?

Age Calculation Tricks:
Step1: Multiply the first number of the age by 5. (If <10,>100, ex: 102, then take 10 as the first digit, 2 as the second one.)
Step2: Add 3 to the result.
Step3: Double the answer.
Step4: Add the second digit of the number with the result.Step5: Subtract 6 from it.
Answer: That is your age.

actuallly this is the concept of separate de 2 digit.. xy it separate 10x to 2( 5x+3)-6+y

2)any number
Step1: Think of any number.
Step2: Multiply the number you have thought with 3.
Step3: Add 45 with the result.
Step4: Double the result.
Step5: Divide the answer by 6.
Step6: Take away the number you have thought from the answer, that is, subtract the answer from the number you have thought.
answer:15

actually tis is concept of deduction (2(3x+45)/6)-x

3)
Sequential Inputs of 6
6 x 7 = 42
66 x 67 = 4422
666 x 667 = 444222
6666 x 6667 = 44442222
66666 x 66667 = 4444422222
666666 x 666667 = 444444222222
6666666 x 6666667 = 44444442222222
66666666 x 66666667 = 4444444422222222
666666666 x 666666667 = 444444444222222222

4) square the number
Ex: 47
Step1: Look for the nearest 10 boundary.3 from 47 to 50
Step2: Since we went up 3 to 50, now go down 3 from 47 to 44.
Step3: Now mentally multiply 44 x 50 = 2200 - 1st answer.
Step4: 47 is 3 away from the 10 boundary 50, Square 3 as 9 - 2nd answer.
Step5: Add the first and second answer, 2200 + 9

this is concept of sqr(a)=((x-a)+a)((x+a)-a)=(x-a)(x+a) +sqr(a)

5)guess again
q1) u noe sqr root? hehe (sqrroot(-1))^ 2009
q2) wat is d shape of 1-sin@?
q3) Wat is the largest number in trigonometry ? d answer is =infinity,bt wat is the possible symbol which will get infinity in trigometry ?
q4) i want to put the first of logarithm , d of area and limit (n->infinity) (1 + 1/n)n together
q5) last is combine 1110000 1100101 1101110 1100111 according to ascii system

then combine ans of q1 q2 q3 q4 q5 .. haha
