Parts of an Algebraic Expression
... Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a 1 sign or 2 sign. In 5x 1 3y 1 8, the terms are: 5x, 3y, and 8. When a term is made up of a constant multiplied ...

On the number of polynomials with coefficients in [n] Dorin Andrica
... Abstract Let A be an arbitrary integral domain of characteristic 0 that is finitely generated over Z. We consider Thue equations F(x; y) = in x; y 2 A, where F is a binary form with coefficients from A and is a non-zero element from A, and hyper- and superelliptic equations f(x) = ym in x, y ...

... Alternatively, the sum of the base b numbers 321 and 123 is (3b2 + 2b + 1) + (b2 + 2b + 3) = 4(b2 + b + 1). Note that b2 + b = b(b + 1) is the product of two consecutive integers and, hence, even. Thus, b2 + b + 1 is odd. In base 10, this means that the sum of 86 and the number we want must be divis ...

It remains to determine which of the quaternary algebras (11) satisfying (18) and (19) are equivalent under a linear transformation of the units 1, I, J, ...

So the sums 1 + 1, 1 + 1 + 1, . . . are all distinct (otherwise some such sum would be 0 contradicting the fact that P is closed under addition).
