LINEAR EQUATIONS AND INEQUALITIES IN ONE VARIABLE

RESEARCH PROJECT: The Equal Sign

We have been using the equal sign, =, for some time now. It is interesting to note that the first published use of the symbol was in 1557 with the publication of The Whetstone of Witte by the English mathematician and physician Robert Recorde. Research the first use of the symbols we use for addition, subtraction, multiplication, and division and then write an essay on the subject from your results.
