Sweets from a big box are equally distributed in 10 small boxes. Express the number of sweets in one small box in terms of the total number of sweets. Let us see how practical applications of algebra can be used to solve equations. This is an equation in the variable x. This is the trial and error method where we substitute different values for the variable that satisfies the given equation. An equation has two parts which are connected by an equal to sign.

Four circles balance one square and a circle on the other side. The idea is we have to find out how many circles will balance a square. If we remove the circle from the left pan, we have only the square there. Since we removed a circle from the left pan, we have to remove the circle from the right pan also.

Then there will be three circles in the right pan. Now the balance looks like the one shown on the right. This is called the principle of balances.

Using balancing equations, we can solve equations in a systematic way. Benjamin's mother is three times as old as Benjamin. If Benjamin's mother is 39 years old, find Benjamin's age. The same quantity can be added or subtracted to both sides of the equation.

If the same amount is multiplied or divided on both the sides of an equation, it remains the same. Translating verbal descriptions into algebraic expressions is an essential initial step in solving word problems.

Our first supposition is that Uma buys at least one ball of each kind. In Algebraic Geometry we study geometric objects and their assortment that are characterized by polynomial equations. There are also cubic curves like elliptic curves and quartic curves like lemniscates and Cassini ovals. In real life, algebraic geometry can be used to study the dynamics properties of robotics mechanisms. A robot can move in continuous space with an infinite set of possible actions and states.

When the robot has arms and legs that must also be controlled and the search space becomes many-dimensional. Algebraic geometry is also widely used in statistics, control theory, and geometric modelling. There are also connections to string theory, game theory, graph matchings and integer programming.

The mathematical languages unite fields such as science, technology, and engineering into itself. That is why an individual intrigued by the field of computer programming and coding should figure out how to comprehend and control mathematical logic.

Strong comprehension of algebra incorporates characterizing the connections between objects, critical thinking with restricted factors, and analytical skill development to help execute decision making. One such use of Algebra can be seen in Inference procedures used in Knowledge engineering.

Variables and constant symbols are used as terms representing objects in real life. The knowledge engineer adds a set of facts and specifies what is true, and the inference procedure figures out how to turn the facts into a solution to the problem. Besides, because a fact is true regardless of what task one is trying to solve, knowledge bases can be reused for various tasks without modification. Biostatistics University of Florida. In real life there are a plethora of instances where Algebra is being used.

For instance, take a shopping domain where we need to be budgeted with the cart items and some algebraic formulation is applied. The economy of every country is analysed with the help of economists taking the help of algebra to solve the problems related to debts or loans.
