Roots and Exponents, "Readily Excuse," are results of inverse operations. Their vocabularies look different and sound different, much as those of fractions and long division, but the ideas very similar.

    Usually the topics are taught in two different years in classes with other students. Here, you are the only student and you have a dictionary as reference.

    You will need to know something about

• opposites,
• negatives and positives,
• reciprocals,
• powers including:

  to-the-1, to-the-0, to-the-negative-1, to-the-1/2 (square roots).

    You now have some choices:

    [1] IF the material is new and wish your computer's calculator to facilitate your familiarity with the material, pages are written about your computer's calculator which also focus on some of the topics you need. Go there.

    [2] IF you do not feel ready for the work shown in the WARM UP below (including work with negatives and positives), then do "enough" self-directed RESEARCH using the word groups, essay, and words listed below first.

    [3] IF you are ready for the WARM UP, please go there now.

    I WOULD PREFER YOU CHOSE [3] OR [1].
