Mathematical Modeling

Turning Problems into Math

Mathematical modeling means using math to represent real-world situations. You make a model by:

  1. Understanding the problem.
  2. Creating equations or graphs to represent it.
  3. Using math to make predictions or decisions.

Examples in Everyday Life

  • Predicting how much money you'll have after saving for several months.
  • Figuring out how long it will take to bike a certain distance at a given speed.

Why It Matters

Modeling helps you solve real problems, from science experiments to planning a party budget.

Modeling Tips

  • Identify what you know and what you need to find.
  • Choose the right math tool (equation, table, graph).

Examples

  • Write an equation for renting a bike: $10 plus $2 per hour is \( y = 2x + 10 \).

  • Graph the relationship between hours studied and test scores.

In a Nutshell

Modeling turns real-life scenarios into mathematical problems you can solve.
