A mathematician has developed an algebraic solution to an equation that was long thought to be unsolvable. A groundbreaking ...

Not everyone was a whiz at math in school ... Let's take a look at a prime example. In theory, the equation 46+4×4-4×2=? shouldn't pose a problem for anyone who has completed primary school.

For example, the simultaneous equations \(3a + 2b = 17\) and \(4a - b = 30\) have no common coefficient as the coefficients of \(a\) are 3 and 4, and the coefficients of \(b\) are 2 and -1.

For example, the simultaneous equations \(3a + 2b = 17\) and \(4a - b = 30\) have no common coefficient as the coefficients of \(a\) are 3 and 4, and the coefficients of \(b\) are 2 and -1.

The entry, reproduced as the boxed equation in the photograph ... a real part and an imaginary part, for example 4+3i. The simplest of these is the number i, which appears as the point one ...
