What does - mean in MATHEMATICS
The minus sign ( - ) is a mathematical symbol used to denote subtraction, difference, and a negative number. It is one of the most commonly used symbols in mathematics and can be seen in all levels of mathematics from basic arithmetic to more advanced subjects like calculus. The minus sign is also known by other names such as subtract, minus sign, negative number sign, or just “subtract”. In addition to its use in mathematics, the minus sign has been used in many other fields as well including computer programming languages and logic notation.

Meaning In Science
In science, the minus sign (-) has a variety of meanings depending on the context. Most generally it indicates a decrease or subtraction from some quantity or condition. For example, when describing changes in temperature over time (such as atmospheric temperature), the minus sign is often used to indicate a decrease in temperature. The minus sign can also be used when discussing electrical charge; a negative charge would be represented with a minus sign while a positive charge would be denoted with a plus (+) symbol. Additionally, in chemistry it may signify the reduction state of an element; when an element releases electrons it becomes negatively charged and thus “negative” in terms of charge.
Full Form
The full form for the minus sign "-" does not exist as it is simply an operator that represents subtraction, decrease or negation. As previously mentioned it is one of the most commonly used mathematical symbols and can appear alone or alongside another operator such as "+" (plus). Although there are alternative names for the symbol such as subtract, difference, or negative number sign they all refer to the same operation/concept – that of reducing something by taking away some amount from it.
What Does - Stand For?
When posed with this question we can provide two answers depending on how we interpret the question itself. The first answer would simply be that - stands for subtraction since it is an operator which denotes subtracting one value from another or reducing something by taking away some amount from it. The second answer could be that - stands for nothing since technically speaking there is no full form associated with this symbol – it simply serves as an indicator of subtraction without any particular meaning beyond that operation/concept.
Essential Questions and Answers on Subtraction in "SCIENCE»MATH"
What is addition?
Addition is a mathematical operation that combines two items into one. The result of adding two numbers is the sum of those numbers. For example, 1 + 1 = 2.
How do you calculate subtraction?
Subtraction is the opposite of addition; it involves taking one number away from another to find the difference between them. For example 10 - 7 = 3.
What is multiplication?
Multiplication is an arithmetic operation in which a number or quantity is repeated a specified number of times, typically indicated by an asterisk or cross symbol (x). For example 5 x 8 = 40.
What is division?
Division is the process of dividing one number by another. It's used to find how many times one number goes into another, and can be written using either a fraction or with the division symbol (÷). For example, 20 ÷ 5 = 4.
What are fractions?
A fraction represents part of a whole or group. Fractions are written as numbers with lines separating them into two parts (numerator and denominator), indicating how many parts there are and how many parts make up the whole. For example 3/4 indicates that there are three out of four parts in the given fraction.
How do you add fractions?
Adding fractions with like denominators involves finding the sum of both numerators and keeping the same denominator for your answer. For instance, if you want to add 1/4 and 2/4 together, first add their numerators (1 + 2) to get 3 then keep the same denominator 4 so your answer would be 3/4.
How do you subtract fractions?
Subtracting fractions with like denominators involves subtracting both numerators and keeping the same denominator for your answer. For instance, if you want to subtract 1/5 from 3/5, first subtract their numerators (3 - 1) to get 2 then keep the same denominator 5 so your answer would be 2/5.
How do you multiply fractions?
Multiplying fractions requires multiplying both numerators and both denominators together in order to get your answer. For instance, if you want to multiply 2/3 by 4/5 first multiply their numerators together (2 x 4) to get 8 then multiply their denominators together (3 x 5) which gives 15 so your answer would be 8/15.
Final Words:
In conclusion, we can say that - stands for two separate things depending on how you interpret its usage; either subtraction (as an operator) or nothing (as there is no literal full form associated with this symbol). No matter what interpretation you choose however both explanations demonstrate why - remains one of the most widely recognized symbols across all disciplines – its simplicity allows it to easily convey certain concepts without any difficulty regardless if those concepts pertain to mathematics or any other field of study.
