# Properties of Arithmetic

\[ ({2007} \times {20062006}) - ({2006} \times {20072007}) = \ ? \]

\[ 1 + a + 2b + 3c + 2ab + 3ac + 6bc + 6abc\]

We are given that \(a = \color{red}{999} , b = \color{blue}{666} , c = \color{green}{333}\). Find the value of the expression above.

Hint: Try to factorize the expression.

\[\large\dfrac{x^2+x^4+x^6+x^8+x^{10}}{x^2-x^4+x^6-x^8+x^{10}}=\dfrac{x^3+x^5+x^7+x^9+x^{11}}{x^3-x^5+x^7-x^9+x^{11}}\]

Does the equation above hold true for all real \(x\ne0\)?
