If you correctly recall the elementary trick for order of operations, solving this problem should be a breeze.

Abstract: Nonlinear equations systems (NESs) are widely used in real-world problems and they are difficult to solve due to their nonlinearity and multiple roots. Evolutionary algorithms (EAs) are one ...

The internet is torn over an elementary-level math equation, with people suggesting conflicting answers based on their approaches. The simple math problem went viral on X this week, leaving thousands ...

Unless you do it in your day to day job, math can be very easy to avoid once you graduate from school. Suddenly those long, complicated equations that your math teacher swore would be trivial are so ...

Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...

Index laws and the laws of logarithms are essential tools for simplifying and manipulating exponential and logarithmic functions. There is an inverse relationship between exponential and logarithmic ...

Abstract: For a class of nonlinear systems with disturbances, a new fixed time nonsingular sliding mode control (SMC) method is proposed in this paper. A new fixed time stability lemma is proposed ...
