As missions to the Moon multiply, keeping time there is no longer a theoretical problem. Researchers from the Purple Mountain ...

Multiplication is working out how many groups of something you have altogether. Division is working how many you get, after sharing a number between another number. You can use place value charts to ...

Sometimes, it is not possible to divide one number by another exactly. Anything left over that cannot be divided exactly is called a remainder. When you are solving problems and there is a remainder, ...

Abstract: Differential-algebraic equations (DAEs) are a widespread dynamical model that describes continuously evolving quantities defined with differential equations, subject to constraints expressed ...

Among other things, the course includes elementary linear algebra, the solution of equation systems, the theory of functions of several variables, including both unconstrained and constrained ...
