In general you cannot.
Try this for size:
2.892/7+log(37.34)/cuberoot(87)+exp(9.8)
Without a calculator I would not have a hope of evaluating even one of the four elements of the expression. Even with a calculator, many people may well get it wrong!
Yes. Expressions cannot be expressed without variables. There are numerical expressions for ex. 2 + 3 is an expression without variables.
The abstract nouns for the verb to compare are comparison and the gerund, comparing.
a numerical expression is just an expression without any equal or unequal signs, e.g. (a+2b)c or 5x-6y an equation shows two expressions with an equal sign, e.g. (a+2b)c = 53 or 5x-6y = 3k2-7k+21
The phrase "comparing apples to apples" means that you are comparing two or more things that are as similar as possible without being the same thing. Conversly, the phrase "comparing apples to oranges" means that you are trying to compare two or more things that are quite different from each other. A more stringent comparison is that you cannot compare apples and oranges by size, taste, or use, because each is distinct. Comparing apples to apples would be valid because some apples may be preferable to others in these or other ways.
In order to compare numbers, you must have at least two. You can not compare 2 to anything without another number. For example, comparing '2' and '5', 5 would be greater than 2.
Comparing without like or as
There are different methods for comparing the mean, variance or standard error, distribution or other characteristics of populations. Without more specific information it is not possible to answer the question.
Maori chants are ritual, cultural expressions, not artistic, personal expressions.
Station models are useful for comparing local weather conditions because they provide a quick visual representation of key weather variables such as temperature, wind speed and direction, cloud cover, and atmospheric pressure at a specific location. By using station models, meteorologists and weather enthusiasts can easily compare conditions at different locations and track changes over time without needing to interpret extensive numerical data. This helps in identifying patterns and trends in weather data more efficiently.
It's quite silly to compare socialism or communism with capitalism without comparing them to each other.
All humans perform universal facial expressions that give away their feelings. Babies can show these expressions without having to learn them because they are born with the 'instinct'.
You can estimate your weight by comparing yourself to objects of known weight. For example, by using a bathroom scale and balancing it without weighing yourself, you can see how you compare in weight to the scale to make an estimation.
