All these calculations are nothing but Algebra whose concept of linear or quadratic equation balancing comes into play when these predictions are made. The Father of Algebra mentioned in the first half of this section did make use of Algebra to contribute to various findings related to astronomy and astrology in his time.

7. Technological developments

Any innovations around us could not be possible without Algebra. If you decode the functioning of an LED TV and dig into its internal atmosphere, you will find that these TVs are making use of planes, angles, and axes as variables and apply algebraic concepts in the development of various types of screens.

Technological developments

Thus, developmental aspects are a sum total of the materials and their placement within the TV’s environs, allowing users to have a variety of monitors, and other functionalities. The variations in monitor sizes without the problem of distortion of the picture are achieved with the help of Algebra knowledge that allows designers to fiddle with a variety of dimensional options.

8. Budgeting

Running a family’s or business’s expenses involves a budgeting process. We all are budget planners in some or the other capacity.

And, apparently, we make use of Algebra in structuring the budget so that all expenses, intended investment aims, and the overall cash in hand can be fixed and altered.

For example, when you are trying to find the correct quantity of purchase of rice, you try to find its per pound cost to know about the real savings you are likely to make. Similarly, when you are choosing between various weights of the product and trying to match them with the appropriate vehicle that could carry it comfortably, you are making use of Algebra in a real-life situation.

10. Doing Interior and Landscape designing

Not only interior planning or landscape designing, in fact, but the whole of the Architecture stream employs Algebra. When the designers are trying to find the correct elevation or try to arrive upon the collection of things required to do a space, they make use of data like measurements of the space and that of the items to fit in.

This is the Algebra used in real life that helps to understand how things are going to amplify the looks of the space and will contribute to the overall appearance of the space.

Similarly, in an office environment, the decisions like moving to larger spaces to accommodate people or designing cabins are some of the premises where Algebraic calculations come into play.

11. Computer Programming

While coding, the programmer is making use of datasets, strings, and variables. They assign conditions in the use of these strings and establish relationships, which ultimately result in an action on the front end.
