#APPROXIMATELY EQUAL SYMBOL PLUS#

≪ ≫ These symbols are less common and mean much less than, or much greater than. ≤ ≥ These symbols mean ‘less than or equal to’ and ‘greater than or equal to’ and are commonly used in algebra. This symbol means greater than, for example 4 > 2. The two sides of a relationship indicated by this symbol will not be accurate enough to manipulate mathematically.

≈ means approximately equal to, or almost equal to.

This is similar to, but not exactly the same as, equals. In computer applications (like Excel) the symbols mean not equal. You may also come across other related symbols, although these are less common: 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. The = equals symbol is used to show that the values on either side of it are the same. is used in spreadsheets and other computer applications. ÷ is used commonly in handwritten calculations and on calculators, for example, 2 ÷ 2. These symbols are both used to mean division in mathematics. For example, if you see a number written outside brackets with no operator (symbol or sign), then it should be multiplied by the contents of the brackets: 2(3+2) is the same as 2×(3+2). Less commonly, multiplication may also be symbolised by a dot. The symbol * is used in spreadsheets and other computer applications to indicate a multiplication, although * does have other more complex meanings in mathematics. These symbols have the same meaning commonly × is used to mean multiplication when handwritten or used on a calculator 2 × 2, for example.

The − symbol is also commonly used to show a minus or negative number, such as −2.

− is used when one or more numbers are to be subtracted, for example, 2 − 2.

This symbol has two main uses in mathematics:

Our page on Positive and Negative Numbers explains that a number without a sign is considered to be positive, so the plus is not usually necessary. The + symbol can also be used to indicate a positive number although this is less common, for example, +2. The addition symbol + is usually used to indicate that two or more numbers should be added together, for example, 2 + 2.
