comment Adding and multiplication in jacobian coordinates
I think it means a multiplying a point by a scalar just like you said. Thanks a lot for the help, @CodeslnChaos and Barack Obama

comment Adding and multiplication in jacobian coordinates
Thanks a lot for your response. The curve equation is ${y^2}={x^3}+ax+b$. And i need to find formulas for addind and multiplication of 2 points (X,Y,Z) over this curve such that $x=\frac{X}{Z^2}, y=\frac{Y}{Z^3}$.
