Mathematics is applicable in various traditional fields of engineering: mechanical and electrical engineering are among them. Mathematics is used in computer engineering too.

Mathematical logic is used in the decision making, so it is used in computer programming. As Venn diagrams are helpful in understanding the concepts of logic, they are also helpful in the programming. For instance, De Morgan's laws are used in writing statements involving decisions and Venn diagrams are helpful in understanding these laws.

Calculations are also important in the science of computers. The text you read on the computer screen is presented in a particular format. Calculations are certainly needed for these.

Geometry is used in the development of graphics. Actually a graphics screen resembles the co-ordinate plane. Just as we have points in the co-ordinate plane, we have pixels on the graphics screen. Though there are endlessly many points in any bounded part of the plane, while the number of pixels on the graphics screen is limited, yet the techniques of coordinate geometry can be used in drawing various figures on the graphics screen.

Various transformations play a part in the development of software. Two such transformations are famous as 'pop and push transformations'. As the graphs are useful in understanding different kinds of transformations, these help understand, in particular the Pop and Push transformations too.

The classical computer programming language namely 'the C language' makes a lot of use of mathematics. Different graphics commands of this language are based on the mathematical logic. The commands for making the background make use of hexadecimal numbers.
