Homework Help Complex Problems – Moving Deeper into Concepts

As you move deeper into each textbook (Algebra, Geometry, Calculus, etc), the problems will contain several concepts you’ve learned earlier – all in one problem.  This complexity can make it difficult to find the “how-to” or examples in the book to help us understand how to work it.

Recently, we received this question from our student support page: There doesn’t seem to be any examples or teaching that I can find that helps me solve this problem.

This is a common question – not this particular problem, but in general, as the problems develop into including several simple concepts stacked into compound calculations. However, the explanations are there, they just may be back a few, or several, chapters.

For example, Jacobs Algebra Chapter 12 Summary and Review Problem 14h.

Concepts include but are not limited to:

  • Chapter 12: Square Roots. Simplify radical as much as possible. Example of this step page 480-481
  • Chapter 5: Equations in One Variable. Specifically for this review problem, Equivalent Equations (Lesson 3) page 162-163.
  • Chapter 12: Square Roots: Radical Equations. Page 505 has examples of squaring both sides to eliminate the radical.

Math builds on itself. As you learn more and more concepts, the problems reach back and build on calculating and analyzing skills learned earlier in the book or even in an earlier course. These complex problems can be hard to find “how-to” when we just can’t see it! The solutions manual is a good resource to help with steps, but sometimes even with those steps, we need to see where it was explained or taught.

We are here to help! Send us your homework questions and let us help. Filling out this form makes it easy to be sure you’ve told us what we need to know to help you, but you can also send an email to support@askdrcallahan.com.

Be sure to tell us:

  1. the course,
  2. the chapter,
  3. the lesson,
  4. the problem,
  5. YOUR issue as best as you can explain it.

We love to help.

When your child is actually ahead, not behind.

I am used to having parents tell me that they think their kid is behind, missed something in 3rd grade, or has a suspected learning disability. That dialogue is almost always the first thing parents say when they are outlining why they need help from a math tutor. For some students, however, they do not need to be held back or to see a doctor. What they need is to move ahead and go on to the next step.

Innovation in Life Starts with Higher Level Math in High School

Are you panicked about Calculus? Maybe it’s time to be more panicked about a world where no one builds bionic arms, solves environmental problems, or seeks a cure for cancer–because that’s the reality you’ll have if kids stop taking higher math in high school.

Real World Math | The Algebra of Planning a Road Trip

When you plan a road trip, you use math literally every step of the way. What you may not know, however, is the right math term for what you’re calculating. So today, I’m going to walk you through a few steps of planning a road trip so you can see how Algebra helps you get from point A to point B successfully.

3-step project idea to help you learn why learning math is important

Around the world, education is not as often available as it is in more developed countries. Too many high school students that I work with here in the US take math education for granted. You see, a global perspective on mathematics and it’s place in the world is a problem we, as the adults, created–or at least allowed. Here’s what I think we can do to change that narrative and start a conversation that creates a better perspective on math and education in general.
