Making video games requires several key skills, all of which require some knowledge of math. Occupations in the video game field are divided into several professions. One of these skills or professions is a game programmer/programming. The following is an example of the Programming Language used in Microsoft.XNA.*:

double angle = MathHelper.TwoPi / points;

pointList = new VertexPositionNormalTexture[points + 1];

pointList[0] = new VertexPositionNormalTexture(

Vector3.Zero, Vector3.Forward, Vector2.One);

for (int i = 1; i <= points; i++)


pointList[i] = new VertexPositionNormalTexture(

new Vector3(

(float)Math.Round(Math.Sin(angle * i), 4),

(float)Math.Round(Math.Cos(angle * i), 4),



This function is used in Microsofts XNA dev kit to render a 3d primitive in 3d space. You will see subsets and templating here but it is very HELPFUL to know what these functions do.

So with Math.Round obviously rounds, Math.Sin and Math.Cos are Trig./Geometry functions that times the angle of a triangle with the integer length of a side between angles, which will give you 3d coordinates so the computer/console knows where and how to render the object relative to the rendering window(what appears on screen/FOV).

If you want to make games it is true that you do not need to be a rocket scientist or an English major, however, knowing math and having a strong ability with it is pretty much necessary.

I recommend:

Physics (Whats a game with no real life laws?)

Linear Algebra

Algebra 1 & 2 (minimum)


With the above skills in hand you could build your own game engine. Now if you are going to buy middleware to handle all math functions you would more and likely be able to make it with Alg. 1 and 2.

Talk with your advisor as they will know more just never accept an answer that says you don't need to know math to develop games or any software as these are false in an industry that is BOUND by math.

Oh and further, take a look at RAYCASTING and you will clearly see why understanding math is important.

Building math skills is great, what better way to give your child in a video game. There are many different games out there that can help build math skills. A couple are at the math playground, ict games and donkey kong math are some great places to start.

math and video games dont go toether

Wii and DS both offer quite a few educational video games. DS has some that are specifically for math.

VideoGames require math knowledge to make. Many games can teach you educational skills.

Almost all games have some sort of math in them. Of course they are used for fun, but they also teach important skills, like linear equations.

People that are good at learning math usually are good at learning how to program. Programming is a big aspect of making video games.

There are many math related board games depending on the type of math that is desired. Monopoly, Uno, Stratego, and Yahtzee all use math skills.

because they are both not very good

Video games enhanced the younger generation by improving skills such as organizatio, math, critical thinking skills and hand-eye coordination, creating a sense of community through arcades/multiplayer games, instilling in them a healthy sense of competition and a respect for rules, and, in the case of at risk youth, keeping them off the streets by providing them with entertainment.

Some of games are designed to develop math skills. otherwise they are just good for your mind. Meaning that almost all of the games have some sort of problem-solving aspect to it.

Specific coding and algorithms are needed to create video games. Especially games that require physics (Racing games, shooting games etc). The more complex the game, the more complex the codes, algorithms (and essentially the math) needs to be.

I have rudimentary math skills.

they teach/ practice skills and enforce them _________________________________________________________________ The games are a fun way for kids to use math, even when they don't know it is math! The games are fun to them, so when they see the question that it is asking but on a test, they remember it. The games also help the kids remember the questions.

It relates by,they have to know MATH before they program the game,or else it might screw up.....

Preschool games can develop all types of skills. Including motor and cognitive skills, they can help your child learn math reading and other subjects.

Most would say some video games are the best for children 6 and over, however, if you could buy your children games that combine learning with fun, that could increase their skills for school. Get board games or maybe even some video or computer games that help them use skills they need to experience and succeed in life. Some good examples are the Leapfrog games that include math, science, and spelling. directly deals with sucessmaker math. It links to websites that have learning opportunities and learning games to help your son improve his math skills.

Video games lower the need for violence. Video games improve dexterity, many surgeons are enjoying improved dexterity. Violent video games help stave off memory loss and loss of function in the elderly. Violent video games helps alzheimers patients. Video games can provide an environment for the normally friendless to have friends. Video games can help people see a different form of view in a non confrontational way. Video games can lead to marriages, or divorces. Video games is a clean form of entertainment, and usually cheap as well. Playing video games leaves teenagers less time to form, or enroll into gangs. Video games can encourage reading, and can boost vocabulary. Games can teach the values of math (pokemon card games, Dungeons and Dragons). Games can encourage writing skills.Theres more, but i got bored of typing

Most Definitely. Math is Incorporated into many video games and some games such as math blaster are all about doing math alone. Others such as Brain age or Flash Focus are also used as teaching tools. But even in your standard adventure or First Person Shooter game you are almost always subconsciously doing math and stimulating parts of the brain not used in many other activities.

figuring out the dimensions of a map,shape,or anything that needs to be measured to make sure it is the correct size it needs to be.

And how else do you expect to improve your math skills, if not by studying???And how else do you expect to improve your math skills, if not by studying???And how else do you expect to improve your math skills, if not by studying???And how else do you expect to improve your math skills, if not by studying???

In order to get your kids to do math, you have to make it fun for them. For example, you can get them to play math games;make up funny and crazy stories that involve math;etc. Be creative!
