What is plus + sign
Generally speaking, a plus (notated with the sign “+”) is a sign which is put among two digits (i.e., numbers) to signify that the 2nd number is being added to the first one. The plus sign may also be placed right before a number to indicate that the number is more significant than zero (e.g., +3), and right after a number as well, to represent a number which is far more than a minimum number or even an amount (e.g., 18+).
The plus sign, +, is simply a binary character which, in most cases, indicates addition, as in the following example: 2 + 3 = 5. Besides, the plus sign can serve as a unary character that leaves its operand unchanged, for instance, +x, meaning the same as x). That explanation can be used when desired to foreground digits’ positiveness, particularly in contrast with the negative numbers, such as +5 versus −5.
The plus + sign may also designate other multiple operations that vary across the mathematical system right under consideration. Like vector spaces or matrix rings, several algebraic structures have a function called or is equivalent to some addition. It is quite convenient to use the plus + only to stipulate commutative operations. The plus symbol is also commonly used in physics and chemistry.

What are the common uses of the plus sign?
In this section, you can take a look at the various uses of the plus sign, such as:
Use #1: The plus + sign is most frequently used in math and programming to add two or more digits or a programming operator.
Use #2: Plus + is used in a math formula to signify addition. For instance, in this formula you can see that the number 2 <plus> 1 is equal to number 3; like: 2 + 1 = 3.
Use #3: A plus + is also used in a URL. In a URL, the plus sign is a popular method used to notate a space since spaces are not allowed in URLs.
Use #4: Plus + in a shortcut key – In a shortcut key, the plus + sign is used to specify two or more keys pressed simultaneously. For instance, "Ctrl + A" means to press the "Ctrl" key and then press the letter "a" to select all text. The plus + sign can also be used as a shortcut. For instance, in a browser, you can press "Ctrl" and the "plus" key to zoom in on an image or text.
Use #5: A plus + is used in a regular expression to match one or more times. For instance, in a regular expression, all the letter "z" will be replaced with a single letter "a." Hence, the "z" will become "a," "ZZ" becomes "a," as of "zzz," it will become "a," and so on.
Use #6: Plus can be used as an increment a variable in programming. Two pluses ++ next to each other in programming is commonly known as a shorthand method of incrementing a variable's value. For instance, if you had a variable called "$count" and that variable was equal to "10", you wrote $count++. However, in other various programmings, the sign would increment by one and become "11."
Use #7: The plus + key is generally shared with the equals key on U.S. keyboards, shown next to or even above the equals character. To create a plus + sign, you will have to hold down the "Shift" key on your keyboard and also at the same time hit the backslash key.
