About this guide
Five complete lessons, 75 worked examples, 25 topic-practice exercises and 30 mixed activities. Mathematical questions use the practice bank; workflow and written responses include model answers for self-review.
How to use this guide
Build on your mathematics with effective tool use
The four content-domain guides explain the mathematics; Essential Foundations builds the prerequisites. This guide teaches you to carry those ideas into a calculator and a digital test without losing their meaning. It is not an additional official SAT content domain.
Use the graphing calculator for equations, tables, and models. Use numerical calculation when arithmetic is the bottleneck. Use mental work or algebra when the structure already gives the answer. A long sequence of keystrokes is not automatically an efficient method.
Learn in three passes
Understand. Read a section’s lessons, then attempt each worked example before opening its explanation. Write the target and predict the rough result first.
Operate. Reproduce the entries in the SAT-specific Desmos testing calculator or a Bluebook practice environment. Inspect the displayed fraction bars, exponents, table headings, angle mode, and graph window rather than trusting your keystrokes.
Transfer. Complete the exit check and the mixed sets with the lessons closed. Record both mathematical errors and tool errors. Finish with the digital rehearsal in Review and reference.
What the examples contain
Each example supplies a recognizable problem structure, a suitable tool or manual method, an interpretable result, a check, and a specific trap. Foundation isolates a skill; Standard combines skills; Challenge exposes a subtle condition. Examples 5.13 and 5.14 are explicitly labeled Workflow scenarios, not mathematical SAT items.
The 25 section-exit questions and 30 mixed questions include mathematical problems and tool-decision tasks. Every one has an explanation. These fixed practice sets are not adaptive tests, and their raw scores do not predict an SAT scaled score.
Read calculator entries as mathematical recipes
Monospaced lines show what to build in the expression list, not a guaranteed literal paste sequence on every keyboard. An underscore creates a subscript, a caret creates an exponent, and a slash creates a fraction. Move the cursor out of a template before continuing. The typeset formula and stated output let you verify the resulting structure.
Scope and version note
Policy and interface guidance was checked against official College Board and Desmos documentation in September 2026. Testing calculators can differ from the public calculator; start with the SAT selection on Desmos’s testing page and confirm the tools in Bluebook.[3][4] Mathematical figures here are original explanatory diagrams, not Bluebook screenshots. The mathematical results were independently checked. Calculator recipes follow official documentation; they were not executed in Bluebook for this guide.
