Let
$$p(x,y) = a_0 + a_1x + a_2y + a_3x^2 + a_4xy + a_5y^2 + a_6x^3 + a_7x^2y + a_8xy^2 + a_9y^3.$$Suppose that
\begin{align*}
p(0,0) &=p(1,0) = p( - 1,0) = p(0,1) = p(0, - 1)= p(1,1) = p(1, - 1) = p(2,2) = 0.

p(0,0) &= a_0 = 0\\
p(1,0) &= a_0 + a_1 + a_3 + a_6 = a_1 + a_3 + a_6 = 0\\
p(-1,0) &= -a_1 + a_3 - a_6 = 0.
\end{align*}Adding the above two equations gives $a_3 = 0$, and so we can deduce that $a_6 = -a_1$. Similarly, plugging in $(0,1)$ and $(0,-1)$ gives $a_5 = 0$ and $a_9 = -a_2$. Now,... |

Find the area of the region described by $x \ge 0,$ $y \ge 0,$ and

### Response:
| Let $n = \lfloor x \rfloor,$ and let $\{x\} = (0.x_1 x_2 x_3 x_4 \dots)_{10},$ so the $x_i$ are the decimal digits. Then the given condition becomes
\[\lfloor y \rfloor \le 100 \{x\} - \lfloor x \rfloor = (x_1 x_2.x_3 x_4 \dots)_{10} - n.\]Since $\lfloor y \rfloor$ is an integer, this is equivalent to

How many three-digit numbers satisfy the property that the middle digit is the average of the first and the last digits?
### Response:
| I think we should start with looking at the possible values of the middle digit. For example, if the number was $a 4 b$, then $4 = \frac{a+b}{2}$. Right, so that means that $a+b=8$. We also know that the number can't be a three-digit number if $a=0$. So $a$ can be any digit from 1 to 9. Right. So $a+b=2m$. If we know t... |
