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:
1 2 3 4 5 TO 100 PLUS
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.
