Multiplication Sign — Definition, Formula & Examples
The multiplication sign is the symbol that tells you to multiply two numbers together. The most common form is the times sign (×), but a dot (·) and an asterisk (*) are also used.
A multiplication sign is a mathematical operator symbol placed between two quantities to denote the operation of multiplication, indicating that the product of those quantities is to be computed. Standard notations include ×, ·, and juxtaposition of variables (such as for ).
How It Works
Place the multiplication sign between two numbers to show they should be multiplied. In early math, you typically use the × symbol, as in . Once you start using variables in algebra, the × sign is often replaced by a dot () or dropped entirely ( means ). This avoids confusing the × symbol with the variable . On calculators and computers, the asterisk (*) is the standard multiplication symbol.
Worked Example
Problem: Write and solve: 6 groups of 7 using the multiplication sign.
Write the expression: Use the × sign between the two numbers.
Multiply: 6 groups of 7 equals 42.

Why It Matters
Recognizing different forms of the multiplication sign is essential when you move from arithmetic into algebra, where × is replaced by · or dropped altogether. It also matters when typing math on a calculator or computer, where you need to use the * key.
Common Mistakes
Mistake: Confusing the × symbol with the variable in algebra.
Correction: In algebra, use a dot (·) or parentheses instead of × to avoid mix-ups. For example, write or rather than .
