Integers whose absolute values are less than 6 are -5, -4, -3, -2,-1, 0, 1, 2, 3, 4, 5, and the product is 0.

2. The number of whole points covered by line segment AB is 2005.

3. Finite and infinite decimals can be regarded as rational numbers, and infinite acyclic decimals are called irrational numbers.

4. Because A and B are opposites, A+B = 0; Because c and d are reciprocal, CD =1; Because the absolute value of m is 2, m is 2 or -2. A+B/A+b+ C+M-CD = 0/C+2- 1 = 2- 1 = 1 or = 0/C+(-2)- 1 =-2- 1。
