Here are examples....
1. The offending math texts call π an "irrational" number. As everyone knows, pi (π) describes the ratio between the circumference of a circle and its radius, a value that is approximately 3.1416. Florida's government knows that math cannot be irrational! This seems to be an attempt to insert Social Emotional Learning into math. Incidentally, Florida is in good company here: back in 1897, the Indiana State House passed a bill that declared that π equals 3.2. (It doesn’t.) Luckily, when the bill reached the Indiana Senate, a Purdue University professor was in the audience, and he helped the senators realize they shouldn't pass it. They didn't.
2. Many of the textbooks refer to "binary" numbers. Of course, if there are binary numbers, there must be non-binary numbers. Are these mathematics textbooks trying to sneak in references to sex and gender? Florida's Education Department can't allow that!
3. Some of the texts describe "magic squares." Magic, of course, is the work of the devil. Florida wisely decided to keep such offensive terms out of its math curriculum.(Aside: a magic square is a square filled with numbers from 1 to N, where the numbers are arranged so that every row, column, and diagonal sums to the same value. These can be fun puzzles for children and adults.)
4. A number of texts introduce the idea of the "golden ratio" and "golden rectangles." Clearly this is a reference to worshipping the golden calf, from the Old Testament, which everyone knows is a false god. What are those math textbooks trying to do here? Making matters worse, the golden ratio is another irrational number! See my discussion of π above.(Aside: two quantities a and b are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities; in other words, if (a+b)/a = a/b.)
5. Most of the offending math texts use the expression "higher power" to refer to exponents rather than to a deity. Obviously this cannot be permitted.6. Let's not forget the Pythagorean theorem. All the math texts describe this creation of a pagan mathematician from ancient Greece, whose philosophy resembled modern socialism.
