10.1–10.7
Gates
The six logic gates — NOT, AND, OR, NAND, NOR and XOR. Every symbol, every truth table, every Boolean expression, learned one gate at a time so the mechanics are solid before you start composing.
The Learning Hub/Topic 10
🔀 Topic 10
Boolean Logic
Three interactive labs fold the whole of Topic 10 into the Learning Hub. The first is the gates — NOT, AND, OR, NAND, NOR and XOR, every symbol, truth table and Boolean expression, the mechanics learned before you compose (10.1–10.7). The second is composition — wiring gates into circuits and moving freely between logic expressions, truth tables and circuit diagrams, then simplifying them (10.8–10.10). The third is purpose — reading a written problem statement and turning its conditions into the right logic (10.11). Each idea is taught, drilled, then tested — work straight through, or jump to the part you need.
10.8–10.10
Composition
Wire the gates together into circuits, then move freely between logic expressions, truth tables and circuit diagrams — and simplify them. Build a circuit and watch it evaluate, input by input.
10.11
Purpose
Read a written problem statement and turn its conditions into logic — spot the inputs, work out the rule, and express it cleanly. The step that connects the exam's words to a working circuit.
