You'll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data!

Complex sentences are simple sentences with dependent or subordinate clauses added to them. Paige and Rosie explain how to spot them and use them in this video.

In this section, we’ll scratch the surface of syntax as it applies to English grammar. Much more can be said about this subject, but we’ll save that for KA Linguistics. ... https://www.youtube.com/watch?v=CsrM_RpqXek Note: All Khan Academy content is available for free at (www.khanacademy.org)
