An apparently easy-looking math problem has left internet users scratching their heads. Give it a try to see if you can correctly solve this elementary-level equation.

Abstract: Control allocation is an important part of a system. It implements the function that map the desired commanded forces from the controller into the commands of the different actuators. In ...

Abstract: Two finite-time recurrent neural network models (abbreviated as FTRNN-1 model and FTRNN-2 model) are proposed and investigated for solving quadratic minimization problem that is widely used ...

Simple math equations grow harder when we're out of practice. As time goes on we forget the elementary rules of math and compound problems become more and more challenging. That's why a simple math ...
