11. This results in a Laurent polynomial with integer coefficients in the variable t ^ { 1 / 2 }. 12. As one is working with polynomials with integer coefficients , this greatest common divisor is defined up its sign. 13. For input polynomials with integers coefficients , this allows to get Sturm sequences consisting of polynomials with integer coefficients. 14. For input polynomials with integers coefficients, this allows to get Sturm sequences consisting of polynomials with integer coefficients . 15. Like a determinant, the hyperdeterminant is a homogeneous polynomial with integer coefficients in the components of the tensor. 16. Free abelian groups are formal sums ( i . e . linear combinations ) of elements of with integer coefficients . 17. For some integer " N "; this is a curve with integer coefficients with an explicit definition. 18. :To be technical, the question did specify " integer coefficients , " so you need at least 2. 19. In computer algebra, modular arithmetic is commonly used to limit the size of integer coefficients in intermediate calculations and data. 20. On the other hand, the reduced echelon form of a matrix with integer coefficients generally contains non-integer coefficients.
