100^2 - 99^2 + 98^2 - 97^2 + 96^2 - 95^2 + ... + 2^2 - 1^2 = ?
Since you can notice that there are fifty pairs of n^2 - (n-1) ^2,
n^2 - (n-1)^2 = n + (n - 1)
Thus 100^2 - 99^2 + 98^2 - 97^2 + 96^2 - 95^2 + ... + 2^2 - 1^2 can also be written as
100 + 99 + 98+ ... + 2 + 1 = (100 x 101)/2 = 5050
Can you solve below mathematical equation ?

In the following picture, E is going to slide the object down and as per the terrain and the physics, the round object is going to travel all the way till the end. Now, can you analyze who all people will die when it happens?
As you can see, the person at D dies straight through the object directly. The object then travels further and the see saw thing kills the person at the C as it has spikes below that. Upon falling, over the see saw, the blue object lifts up and then kill the person at B.The solution ends here, but just for fun, The E stands for Ebola and thus the person at A dies as well.Thanks to 9gag for this gif.
Suppose there are 100 people standing in a circle. The first person has a gun in hand. What he has to do is shoot the second person and then pass the gun to the third person. Now, the third person kills the fourth person and gives gun to the fifth person.
This process is carried till there is only one person surviving. Can you find out who survives at the end ?
73rd
There is a simple logic behind solving this question. If the number of people are a power of 2, then the last person standing will be the person who started it.
Now, here we have 100 people. Thus, we will take the highest power of 2 which is less than the total number which is 64.
100 - 64 = 36.
This means that 36 people are killed.
If you go on with the series of even numbers, the 36 people will end at 72 (2, 4, 6, ..., 72). Thus the gun will be in the hand of 73rd person. Now the remaining people are 64 which is the power of 2. Thus the person who will survive in the end will be the 73rd person since he is starting it.
Can you find out which number multiplied by itself will give the output as 12345678987654321 ?
1 * 1 = 1
11 * 11 = 121
111 * 111 = 12321
1111 * 1111 = 1234321

You can use any mathematical symbols in the space provided to make all above algebraic expressions true.
(0! + 0! + 0! )! =6
(1! + 1! + 1! )! =6
2 + 2 + 2 = 6
3 * 3 - 3 = 6
4 + 4 -sqrt(4) = 6
5 + 5 / 5 = 6
6 + 6 - 6 = 6
7 - 7 / 7 =6
8 - sqrt(sqrt(8+8) = 6
(9 + 9) / sqrt(9) = 6
Lena Dunham , Allison Williams, and Jemima Kirke are 3 daughters of a good mathematician "Geroge".
When I asked George the age of their daughters. He replied "The current age of her daughters is prime. Also, the difference between their ages is also prime."
How old are the daughters ?
Lena Dunham : 2 , Allison Williams : 5 and Jemima Kirke : 7
Age diff : 7-2 is 5 , 7-5 is 2 and 5-2 is 3 which all are prime numbers
