If I have understood the question correctly, b is a coefficient of x. b could be 1 but in that case it is not expressly written. Also, b need not be positive.
At the basic level, the modulus of a number or expression is simply the value of the number or of the expression. For a positive number the modulus is the number, for 0 it is 0, and for a negative number, x, it is -x (which is positive).
It is the decimal expression of a positive rational and real number.
* If "a" is positive, "-a" is negative.* If "a" is negative, "-a" is positive. * If "a" is zero, "-a" is zero. If you want to force a negative number, you can write -|a|, i.e., the negative of the absolute value.
multiterm mathematical expression: a mathematical expression consisting of the sum of a number of terms, each of which contains a constant and variables raised to a positive integral power
A numerical expression is a mathematical phrase involving only numbers and one or more operational symbols. The following are some examples of numerical expressions. For example, the numerical expression 4 + 20 - 7 in the example above simplifies to the number 17.

A factor is a number or quantity that when multiplied with another produces a given number or expression. A positive factor is a factor that is positive, as opposed to negative.
A factor is a number or algebraic expression by which another is exactly divisible. A positive factor is a factor that is a positive number as opposed to a negative one.

An exponent is the power that a number is raised to. For instance, in the expression 3^2 ("three squared"), 2 is the "exponent" and 3 is the "base." A positive exponent just means that the power is a positive number. For instance, the following expression does not involve a positive exponent: 3^(-2). Horses rule!!!!!
'Polarity' has a number of meanings, generally involving the distinction between positive and negative.
The expression would be abs(4n - 3n) where (4n - 3n) could be simplified to 1n or n. When n is positive, the result is n when n is negative, the result is -n (which will be positive).

"An expression of three terms" means that the expression has three parts, combined by plus or minus signs. Within each of these parts (terms), there can be a single number or variable, or a product or division involving several other pieces.
A numerical expression is a mathematical phrase involving only numbers and one or more operational symbols. The following are some examples of numerical expressions. For example, the numerical expression 4 + 20 - 7 in the example above simplifies to the number 17.
