Define new operation symbol *,
If AB is odd and even, then a * b = (a + b) △ 2;
If it is odd and even, then a * b = (a + B + 1) △ 2;
So, 2002 * 2004 * 2006 * 2008 * 2010 =?

2002*2004*2006*2008*2010
=2003*2006*2008*2010
=(2003+2006+1)÷2*2008*2010
=2005*2008*2010
=(2005+2008+1)÷2*2010
=2007*2010
=(2007+2010+1)÷2
=2009

Enter your question: if the solution of the linear equation AX + B = 0 (a ≠ 0) with one variable about X is negative, what is the sign of a and B? Is the solution positive?

The solution of the equation is as follows
A = 0, B = 0, then x is any number
2. A ≠ 0, x = - (B / a). In this case, if a and B have the same sign, then x is negative; if a and B have different signs, then x is positive
