The big idea
If … then — a conditional rule
An "if-then" rule is a deal: WHEN the if-part is true, the then-part has to happen.
Example: "If it rains, then the ground gets wet." When rain shows up, the rule guarantees wet ground. But if it isn't raining, the rule says nothing at all — the ground might still be wet from a hose or a spilled drink. The rule only "fires" when its condition is met.
If-then is how computers think, how laws are written, and how good arguments are built. Learning to use it carefully is a superpower for school and beyond.
- IF part = the condition you need to check.
- THEN part = what must happen WHEN that condition is true.
- If the IF is false, the rule is silent — not opposite, just silent.
