Let’s face it. In the real world, few scientists or engineers still use calculators and graph paper to work out important equations. They turn to software that can not only check their work, but also communicate it clearly.

Teachers at any level can give their students a professional boost by introducing that same powerful math software early. It’s not difficult to learn, and students leave school with confidence in their skills and mathematical results.

If you’re a teacher who needs help getting started on a curriculum, or if you’re a student learning on your own over the summer break, here are a few tips for jump starting your efforts:

## Resources

Start by exploring these free resources.

• PTC Mathcad Express. You’ll  need good engineering math software. And while some STEM professionals use spread sheets for complicated calculations, communicating via Excel can lead to mistakes and misunderstandings. PTC offers PTC Mathcad Express free, and you can keep most of the functionality for life. [Note that many students qualify for an academic license. Learn more about the academic edition here.]
• PTC Mathcad eLearning Library. Each library offers comprehensive training courses. With the help of these PTC Mathcad tutorials, you can learn about PTC Mathcad Prime’s extensive functionality such as opening and working with Mathcad files, navigating workspaces, defining variables and expressions, and solving equations.
• PTC Learning Connector. For tutorials and self -paced learning, plus reference documents more. You’ll find it all right inside your PTC Mathcad software:

## Examples to Try

Now work your way through these examples. We’ll start with a problem, and show how you would solve it in PTC Mathcad. In other cases, we’ll simply show the problem, and the solution in PTC Mathcad—because, to my point, often the software does the best job of communicating complex problems.

Example 1

Example 2

Check if the numbers 50 and 17 are relatively prime (hint: PTC Mathcad uses gcd for greatest common divisor).

Example 3

Find the smallest common multiple of the numbers: 3, 5, 10.
