For example, if we have the complex number z = 3 + 4i, the real part of z is 3, which we would write as ℝ (z) = 3. Example 3: In set notation, we often use the symbol ℝ to denote the set of all real numbers.Jun 6, 2023 · The = equals symbol is used to show that the values on either side of it are the same. It is most commonly used to show the result of a calculation, for example 2 + 2 = 4, or in equations, such as 2 + 3 = 10 − 5. You may also come across other related symbols, although these are less common: ≠ means not equal. For example, 2 + 2 ≠ 5 - 2.

According to my translation app, it means this: “A is equal to B, B is not equal to A, is less than A, they are logically contradictory” My guess is the translator(s) wanted to skip the part about B being less than A, and either they used a nonstandard symbol or the typesetter could not find a “≠”.

3 Answers. The ⇒ notation means that if the function on the left hand side of the notation is true, then so is the function on the right hand side of the notation. So consider X ⇒ Y. This means that if X is true, then Y is also true. It is necessary to use this sometimes. $\begingroup$ You should always give a full text/internet (or other) reference for a question such as this. Notation varies quite a bit in mathematical literature. Although there are many standard notations that most everyone consistently uses, it's likely that if YOU don't know the notation for something, then it's one of those things that will vary in the literature, hence you need to give a ...2.
