Similarly, the determination of the number of bags of fertilizers needed per acre
requires some calculations. In these two examples, Mathematics enables farmers
to avoid the wastage of financial resources by purchasing only the required amount
of inputs. Mathematics is also used in Agriculture to determine suitable amount
of water to be used in irrigation and the spacing between seedlings. Similarly,
Mathematics is used to determine the investment, expenditure, and savings in Tanzania Institute of Education
cultivating a specific crop, dividing a piece of land, calculating the cost of labour,
and so forth.

Mathematics and Biology
There is a direct relationship between Mathematics and Biology. For example,
normal animal weights, rate of respiration, nutritive values of food, and transpiration
are a few quantities in Biology that can be calculated using mathematical concepts.
Mathematics can also be used to estimate the number of blood cells present in the
body, measurement of blood pressure, and counting sex chromosomes, among
many others.
Mathematics and Chemistry
Mathematics is widely applied in Chemistry to represent and solve various
problems. Some Chemistry activities involve measurement of masses, volumes,
lengths, temperatures and densities of matter. Mathematics is also used to measure
the constituents of mixtures, balancing chemical equations, among many other
applications.

Mathematics and Physics
Physics involves the study of laws, principles, and theorems which governs how matter
works. Most of the quantities in Physics are expressed mathematically through
formulas. In order to understand how to apply the formulas to solve some physics
challenges, knowledge of Mathematics is needed. All the quantities in physics are
expressed in numbers and units which have to be manipulated using the concepts
and skills of Mathematics. For example, to determine the speed of a moving object,
one has to find a ratio between the distance covered and the time taken.

Mathematics and Information and Communications Technology
Mathematics plays a big role in the field of Information and Communications
Technology (ICT). Computer programs, applications, software, and computer
languages make use of mathematical concepts. A common example of the application
of numbers is in defining colours in web development languages. For instance, the Mathematics Form One
HTML (hypertext markup language) and CSS (cascading style sheets) uses colour
notations such as #000000 which represent Black, #008000 for Green and #800000
for Maroon. Furthermore, the digits 0 and 1 are commonly used in computing
systems in computers.
