• Finding the shortest path between two points (known as the “traveling salesman problem”)
• Determining whether a graph is planar
• Encrypting and decrypting data
• Compressing data to save space
• Calculating the probability of an event occurring

These are just a few examples – in reality, math is used in some way, large or small, in most computer science problems. So if you’re interested in pursuing a career in computer science, it’s important to try and acquire at least a basic foundation in math.

## What math do you need for computer science?

There are several things that determine what math is needed for computer science, including the specific subfield you plan to specialize in. The most common math concepts and math courses needed for computer science are:

• Binary and hexadecimal systems: Binary and hexadecimal systems are used to represent numbers in computer science. They are used for tasks such as data storage or database design.
• Number theory: Number theory is the study of the properties of numbers. It is used in computer science for tasks such as cryptography or data compression.
• Boolean logic: Boolean logic is the study of the logical operations AND, OR, and NOT. It is used in computer science for tasks such as circuit design or database query optimization.
• Algebra: Algebra is a branch of mathematics that deals with the manipulation of equations and variables. It is used to solve problems in computer science, such as finding the shortest path between two points or determining the amount of data that can be stored on a disk.
• Geometry: Geometry is the study of shapes and spatial relationships. It is used in computer science for problems such as image processing or 3D modeling.
• Trigonometry: Trigonometry is the study of triangles and their angles. It is used in computer science for tasks such as determining the position of objects in a three-dimensional space.
• Probability and Statistics: Probability and statistics are used in computer science for tasks such as analyzing data sets or predicting the outcomes of events.
• Calculus: Calculus is a branch of mathematics that deals with the study of change. It is used in computer science for tasks such as optimizing code or determining the properties of algorithms.
• Linear algebra: Linear algebra is the study of mathematical problems that can be represented in the form of linear equations. It is used in computer science for tasks such as machine learning or data mining.
• Discrete math: Discrete math is the study of mathematical problems that are discrete in nature, meaning they are not continuous. It is used in computer science for tasks such as combinatorics or error-correcting codes.
• Graph theory: Graph theory is the study of graphs and their properties. It is used in computer science for tasks such as network analysis or data visualization.

If this sounds like a lot of math and causes your head to start spinning already, you should try not to worry. After all, you have probably covered more than half of these topics in high school. The remaining courses, which include advanced calculus, linear algebra, discrete math, and graph theory, are usually covered as part of the computer science curriculum in college.

## Is math needed for computer science difficult?

Math courses needed for computer science can be quite complicated and are often referred to as the most difficult courses in the computer science curriculum. However, taking concepts one at a time and solving plenty of problems tends help most students pass their exams.

It is important to keep up with the homework assignments and not have any overdue tasks in order to stay in touch with the latest material covered in class.

The most important advice we can give you with regards to tackling your math courses in college is:

• Study in groups. Most instructors allow you to form a team with your classmates to work collectively on your homework assignments. This will help you fill in the gaps of concepts you didn’t fully understand in class or tasks that you can’t quite crack on your own.
• Don’t be afraid to ask for help when you need it. Your professors and teaching assistants are there to help you understand the material.
• Do your homework and practice problems on a regular basis. This will help you stay sharp and catch any concepts that you might have missed in class.
• Stay organized and keep track of what topics you have covered and which ones you still need to review. This will come in handy when you have to study for exams.
• Don’t be discouraged if you don’t understand something the first time around. Math is a cumulative subject, which means that each concept builds on the ones that came before it. If you keep at it and review regularly, you will eventually get it!

## Should I study computer science if I am bad at math?

If you are truly passionate about computer science and are capable in other aspects related to this field, you should absolutely study computer science even if you think you are bad at math. The truth is, math is a subject almost anyone can tackle with enough practice and determination.

It is possible you didn’t have an inspiring instructor in the past, which made you believe you are not good enough at math, or a general dislike towards a math class. Things could change in college, so you should give it another try. And even if you don’t excel at math, you can still be an amazing engineer who deals with programming aspects that are only vaguely related to math, such as web development.
