You can move only one digit anywhere for example 110 -102 ( changed the place of 1 in 101).
You are not allowed to change the signs.

You need to move the 2 up :)

Right answer!

White plays first. This is possible when white makes a move with knight.
For example,
White knight moves from g1 to h3,the black pawn move from e7 to e5, again the white knight moves from h3 to g1.

Correct :)

Find the number.
Let the number be x.
If x is divided by 1 the remainder is 0.
if x is divided by 2 the remainder is 1.
if x is divided by 3 the remainder is 2.
and so on..
till
if x is divided by 10 the remainder is 9.

What is the value of x ?

The number is 2519

Find the sequence.
1
11
21
1211
111221
??????
Also explain the logic.

The above puzzle is very tough to solved. But any way, The solution is ..

Here,
1 -> 11 (One 1)
11 -> 21 (two 1)
21 -> 1211 (one 2 and one 1)
1211 ->111221 (one 1, one 2 and two 1)
111221 ->312211 (three 1, two 2 and one 1)

Suppose there there is a no. 5861155
for fist digit (5) that is ONE 5 =15
for second digit (8) that is ONE 8=18
for third digit (6) that is ONE 6=16
for forth and fifth digit (11 (though both the digit is same)) those are TWO 1=21
for sixth and seventh digit (55 (though both the digit is same)) those are TWO 5=25

So, the number is 1518162125

The first student knows their product and the other one knows their sum.
First: I do not know the sum.
Second: I knew that. The sum is less than 14.
First: I knew that. However, now I know the numbers.
Second: And so do I.
What were the numbers?
