In this chapter, we will look at several basic skills and topics that will be used often in calculus: linear functions, solving inequalities, function domains, graphs and graphing, and completing the square. Completing the square will show up in integral calculus when you need to have your function in a particular form.

#### Honor System Information

The Undergraduate Honor Code pledge that each member of the university community agrees to abide by states:

“As a Hokie, I will conduct myself with honor and integrity at all times. I will not lie, cheat, or steal, nor will I accept the actions of those who do.”

Students enrolled in this course are responsible for abiding by the Honor Code. A student who has doubts about how the Honor Code applies to any assignment is responsible for obtaining specific guidance from the course instructor before submitting the assignment for evaluation. Ignorance of the rules does not excuse any member of the University community from the requirements and expectations of the Honor Code.

## Is calculus necessary?

**"Your short article on why we teach calculus is marred with flaws. Why should we continue to teach something just because it has a long tradition? And not having a thing to replace it is your most valid excuse? Also, since when is calculus a part of everyday culture? It sounds like you just want a reason to defend your profession."**

Its a valid point. As a teacher one is of course biased and in general, everybody overestimates and naturally hypes his or her own work or profession.

There is a general principle however: if one wants to replace something, one has to constructively build an alternative which works and demonstrate that it can work on a large scale. Just calling for a replacement is cheap. In the case of calculus, it is not only the results which have an excellent track record (major industries mine calculus today), but also calculus as a "tool to sharpen thinking and problem solving skills" and prepare for other fields.

As replacement of calculus, both discrete math or statistics comes in mind. I myself know that both need solid calculus skills to be used effectively. Whoever calls for using stats as a replacement of calculus does not know stats. Whoever calls for discrete math as a replacement does not understand discrete math. Both fields really only shine if one knows calculus. I love discrete math, (work on it) and statistics (example [PDF]) and even discrete or alternate versions of calculus like here. Unfortunately, in many of todays implementations of discrete math or statistics, the replacement is used as an alternative, the implementation is an excuse to stop practicing harder problems or acquire more sophisticated problem solving skills or to learn harder subjects. Many discrete math courses are a race to the bottom, the reason being the lack of a clear goal to reach. Calculus has the fortune to have a clear goal: the fundamental theorem of calculus (both in single and multivariable calculus), as well as established levels of sophistication like integration skills, knowledge about series and the ability to solve differential equations. Yes, these skills can be hard to reach, but it is worth it. If acquired, the usual discrete math or stats curricula are more rewarding.

Maybe we have to look at history also to see what worked and where things were successful. The biggest advancements in discrete math, physics, statistics,philosophy or computer science were done by people who knew calculus well: Euler invented graph theory and was a master in calculus, Leibniz invented determinants and a computing device and a master in calculus, Newton figured out the laws of gravity, and was a master in calculus, Kepler figured out the laws with which the planets move and was a master in calculus, von Neumann invented modern computers, game theory and was a master in calculus, Archimedes invented countless of machines and was a master in calculus. Kolmogorov wrote the first textbook in probability and was the first put the subject on a solid foundation and was a master in calculus. Riemann dove into the deep mysteries of the prime numbers and was a master of calculus.

## How to improve basic math skills

There are four main ways you can improve your basic math skills:

### 1. Use workbooks

Math workbooks come with many sample problems you can solve to give yourself practice. They will also typically provide some instructions and advice on how to complete the problem, along with answers in the back of the book so you can check to see if you were right. If there&aposs a particular topic in math that you find challenging, look for a math workbook that focuses primarily on this topic.

### 2. Take a class

Many community colleges offer basic math classes, or you can see if there are other adult education classes near you. Another possibility is finding a basic math course online and completing it from home. Math classes provide the advantage of more detailed instruction and the ability to ask questions if you are confused about a topic.

### 3. Ask for help

If you know someone who has strong math skills, you could ask them for assistance. Let them know which areas you find challenging and see if they have any advice. Friends, family members and coworkers can provide a new perspective or perhaps explain things in more relatable terms, which will help to grow your understanding of the topic.

You can also hire a tutor to give you one-on-one attention, either in person or online. This tutor can then provide you with example problems to help strengthen your skills or answer any specific questions you may have.

### 4. Practice

The best way to improve your basic math skills is simply practicing. Using your skills consistently can ensure you maintain your proficiency. Try to avoid using a calculator for every problem you come across or asking someone else to do things for you. Seize every opportunity you can to use your basic math skills, and they will grow stronger over time.
