In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

The future of math education will begin with the divorce of a very long-term marriage between math learning and grade-level instruction. “The Future of Math,” my chapter in School Rethink 2.0, ...

Doctors in England will be encouraged to refer patients to the gym or job coaches rather than signing them off as “not fit for work”, as part of a new government pilot scheme. Health Secretary Wes ...

Standard form close standard formA system in which numbers are written as a number greater than 1 and less than 10 multiplied by a power of 10 which may be positive or negative. can be calculated on a ...

Abstract: This paper presents a novel algorithm and sensor for estimating the position of a magnetic dipole. By transforming Euler's equation of degree -3 into an integral form, we have linear ...

The brainteaser, which has gone viral on X (formerly Twitter), appears to show four basic equations. At first glance, the equation seemingly shows a pattern, one that is not easily cracked. Can you ...

Linear functions are used to model a broad range of real-world problems. The ability to solve linear equations and inequalities is an essential skill for analysing these models. This section covers ...

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 ...

Tired of juggling between Apple Notes and Calculator? A math feature in iOS 18 lets you solve equations instantly with just a quick settings tweak. If you're like most people, the Apple Notes app on ...

A seasonal index is a way of measuring the seasonal variation -- that is, to measure the change that is due to seasonal changes in demand -- of a variable, typically sales. For example, a beachfront ...
