What I learned in the first unit of math 10 honors is how to convert radicals into to mixed radicals in simplest form. I also learned how to use an algebraic procedure to convert a repeating decimal into a fraction. Something I already knew about this unit is what rational and irrational numbers were and finding factors of numbers using the factor tree. Things I want to remember in this unit is how to convert radicals into to mixed radicals, how to convert a repeating decimal into a fraction, and the number theory because it might be useful for later.
