List all the given facts, numbers, and what you need to find. Underline or highlight key data.

S

Set Up the Equation

Translate words into math. Use variables for unknowns. Choose the right formula or create an equation.

E

Tips for Money Problems

Recognize Patterns

Money problems involve counting, prices, or interest. Organize values in tables and track units (dollars, cents).

Define Variables Clearly

Write out what each variable represents. For example: "Let x = current age" is clearer than just "x = age." This prevents confusion when solving.

Work Backwards to Check

Once you have an answer, plug it back into the original problem (not just your equation). Does it satisfy all the conditions stated?

Draw It Out

Diagrams, tables, and visual representations help organize information and reveal relationships that aren't obvious from text alone.
