I suggest you search for some examples to get the general idea. Basically, you convert all units to generic descriptions such as [length], [time], [current], etc.; then you combine them. If you add a length to another length, you get a length again, so:
[length] + [length] = [length]
Similarly,
[length] - [length] = [length]
Please note that:
1) This is different from regular addition or subtraction.
2) You can't add or subtract different types of units. For example, if in a formula you are supposed to add a speed and an acceleration, you get:
speed + acceleration
= [length] / [time] + [length] / [time]2
... which can't be added. If you get something like this, something is wrong with this formula. Such formulae might be used as "rule-of thumb" formulae, and might sometimes give good approximations - but they are not dimensionally correct.
On the other hand, if you multiply or divide units in a calculation, you get the regular product or quotient, for example:
[length] times [length] = [length] squared.

Why dimensional analysis is important?
Dimensional analysis is important because it allows us to check the consistency of equations by ensuring that the units on both sides of the equation are the same. It helps in deriving relationships between physical quantities and simplifies problem-solving by reducing the number of variables involved. Additionally, dimensional analysis can be used to convert units and provide insight into the underlying physics of a problem.

Dimensional analysis.
Why is dimensional analysis useful in scientific calculations and problem-solving?
Dimensional analysis is useful in scientific calculations and problem-solving because it helps ensure that the units of measurement are consistent throughout the calculations. This method allows scientists to check the accuracy of their calculations and identify any errors that may have occurred. By using dimensional analysis, scientists can easily convert units and solve complex problems without making mistakes in the process.

What is the process of writing units of each variable to a real-life problem called?
The process of writing units of each variable in a real-life problem is called dimensional analysis or unit analysis. It is useful for understanding the real-life problem and for checking to see we get a valid answer. Please see the links for additional explanations.
What are the uses of dimensional analysis?
dimensional analysis is very simple method for convert the one system of units into another system of units. And we can check the correctness of the equations. We can show the relations between physical phenomenal quantitatively.VALI
What is dimensional analysis?
a way to analyze and solve problems using the units, or dimensions, of the measurements.
Why is dimensional analysis the most appropriate way to solve in converting measurement?
It is not necessarily the most appropriate way. A proper understanding of the way in which different measurements are related is sufficient - without going into dimensional analysis. Dimensional analysis can be useful for people who have not got their heads around the relationships between units.
What is the method of treating units as algebraic quantities that can be cancelled called?
This technique is usually called dimensional analysis.
What role does dimensional analysis play in answering fermi questions?
Dimensional analysis is a powerful tool in solving Fermi questions because it allows for the manipulation of units to derive relationships between different quantities. By analyzing the dimensions of the given parameters, one can identify relevant equations and estimate the magnitude of the answer. This method helps in breaking down complex problems into simpler components and can provide a rough approximation of the solution without the need for precise calculations. Overall, dimensional analysis aids in structuring the problem-solving process and obtaining reasonable estimates in Fermi questions.
