Key Concepts
New Concept This lesson introduces translating word problems into equations by identifying their plot. Two common plots are combining (addition) and separating (subtraction).
Combining Formula $$ \text{some} + \text{some more} = \text{total} \\ s + m = t $$.
Separating Formula $$ \text{beginning amount} \text{some went away} = \text{what remains} \\ b a = r $$ What’s next This is the foundation for algebraic problem solving. Next, you'll apply these formulas through worked examples and practice problems for both combining and separating scenarios.
