The Product RuleSame base, multiplying? Add the exponents.The Quotient RuleSame base, dividing? Subtract the exponents.The Power of a Power RuleA power raised to a power? Multiply the exponents.Zero and Negative ExponentsWhy anything to the power zero is one, and where a negative exponent really lives.Scientific NotationVery big and very small numbers, written so you can actually compare them.Square and Cube RootsThe numbers worth knowing by sight, and how to simplify the rest.SlopeRise over run, and the four kinds of slope a line can have.Slope-Intercept Formy = mx + b — the form you can graph without doing any working.Three Forms of a LineSame line, three ways of writing it — and what each is good for.Systems of EquationsTwo lines, three methods, and what it means when there is no answer.What Makes a FunctionOne input, one output — and the two tests that check it.Alkaline Earth MetalsGroup 2 — Reactive metals, but noticeably less so than group 1.Transition MetalsGroups 3–12 — The familiar metals.HalogensGroup 17 — The most reactive non-metals.Noble GasesGroup 18 — Full outer shells, so they barely react with anything at all..Linear FunctionsSlope, intercepts, the three forms of a line, and what each one is good for.Exponent & Radical RulesEvery exponent law with a worked example, plus roots and scientific notation.Pythagoras & TransformationsThe theorem, its converse, distance formula, and the four transformations.The Real Number SystemNaturals inside integers inside rationals inside reals, with irrationals beside them.Literary Analysis EssayThesis, topic sentence, quote integration, analysis — with the stems for each.Academic Word RootsThirty roots that carry academic and test vocabulary, with examples.The Periodic TableThe full table by group, with metals, non-metals and the families named.Lab Report GuideWhat goes in each section of a lab report, and how to write a conclusion that scores.The Pythagorean TheoremThe relationship that only works in right triangles — and its converse.Distance and MidpointTwo formulas for the coordinate plane — one is Pythagoras in disguise.TransformationsFour ways to move a shape, and which ones preserve congruence.Scatter Plots and CorrelationReading a cloud of points, and the trap everyone falls into.Volume of Cones, Cylinders and SpheresThree formulas, and the relationship that links them.Newton's Three LawsWhy things move, keep moving, and push back.Plate TectonicsWhy earthquakes and volcanoes happen where they do.Natural SelectionFour conditions, and what the theory does and does not claim.Writing a Thesis StatementArguable, specific, and answering the question actually asked.Integrating QuotationsEmbedding evidence so the sentence still reads properly.The Three Kinds of IronyConstantly confused, and rarely just 'unlucky'.Analysing Word ChoiceThe question behind every 'analyse the language' task.How a Central Idea DevelopsTracking an idea across a whole text, not just finding it.How a Constitution WorksWhat a constitution does, and the three ideas underneath most of them.The Industrial RevolutionWhat changed, why it changed, and what it cost.Angles and Parallel LinesOne transversal, eight angles, and only two different sizes.Linear or Not?Three tests, and what a non-linear relationship looks like.Finding Slope Three WaysFrom a graph, from two points, or from a table.Two-Way TablesTwo categories at once, and the three different percentages you can read from one.Energy Transfer and ConservationEnergy is never lost — but it does become less useful.Reading the Table by PositionWhere an element sits tells you how it will behave.The Electromagnetic SpectrumOne family of waves, from radio to gamma, and what changes across it.Mitosis and MeiosisTwo kinds of cell division doing two completely different jobs.Figurative or Literal?Deciding which meaning a sentence intends, and why it matters.Handling a CounterclaimStating the other side properly, then answering it.Checking a SourceFour questions that catch most misinformation in under a minute.
