The additive inverse is used to solve equations; equations, in turn, are used to model many real-world situations.
Gaussian elimination is used to solve systems of linear equations.

Two-step equations are commonly used in various real-world scenarios, such as budgeting, construction, and cooking. For example, when determining how much of a certain ingredient is needed based on a recipe that serves multiple people, one might set up a two-step equation to solve for the quantity required. Similarly, in finance, individuals can use two-step equations to calculate the total cost of items after applying discounts or taxes. These equations help simplify complex problems into manageable steps for effective decision-making.
Matrices are tools to solve linear equations. Engineers use matrices in solving electrical problems in circuits using Thevenin's and Norton's theories.

There is no way of knowing if new technology will solve world problems since we have no way of knowing what new technology is going to be developed, or for that matter, what world problems will exist at the time that technology is developed. It is possible that new technology will be used to solve world problems, and it is also possible that new technology will be used to make world problems worse. We will have to wait and see.

William Steward Burroughs invented the calculator because he wanted the world to know hot to solve equations and problems and figure out how to correctly do a math problem. he also wanted you to always get an answer right when using a calculator
