Test analysis: according to the definition of absolute value and integer, the result is obtained directly;
From |a|=3 and |b|=2, we can get a = 3 and b = 2, which can be solved in four cases.
According to two negative numbers, compare the larger absolute value with the smaller absolute value;
Every monomial in a polynomial is called a polynomial term, and the highest degree of these monomials is the degree of this polynomial, which can be judged according to this definition.
Xiao Ming made a mistake and changed it to "There are 9 integers whose absolute values are not greater than 4."
Xiao Ding is wrong, "If =3, =2, the value of is 5 or -5, 1 or-1."
Xiao Pengcuo, "Polynomials are quadratic trinomials."
Xiao Liang was right.
Comments: This problem belongs to the basic application problem, and it can only be completed if students master the definitions of absolute value and integer, the comparison of rational numbers, the addition of rational numbers and the definition of polynomials.
