Robert Recorde Hope
The first English mathematician to use the modern symbol of equality (=) was Robert Recorde. He introduced this symbol in his work "The Whetstone of Witte" published in 1557. Recorde chose the symbol because he believed that "no two things can be more equal" than two parallel lines, which he used to represent equality.

The symbol for pi (π) represents the mathematical constant that is the ratio of a circle's circumference to its diameter. It was first introduced by the Welsh mathematician William Jones in 1706. The symbol was later popularized by the Swiss mathematician Leonhard Euler in the 18th century.
