3×p

3×p is a mathematical expression commonly encountered in algebra. It represents the product of the number three and a variable, typically denoted by the letter 'p'. The '×' symbol signifies multiplication, though in algebraic contexts it is often omitted, and 3p is understood to mean 3 times p.

The value of 3×p is dependent on the value assigned to the variable 'p'. For instance, if p equals 5, then 3×p would be 3 multiplied by 5, resulting in 15. If p were -2, then 3×p would be 3 multiplied by -2, yielding -6. This expression is a fundamental building block in forming more complex algebraic equations and functions.

Understanding the concept of 3×p is crucial for solving linear equations, simplifying expressions, and performing various algebraic manipulations. It illustrates the principle of variable substitution, where a letter stands in for an unknown or changeable quantity. The coefficient, which is the number 3 in this case, indicates how many times the variable 'p' is being added to itself. Therefore, 3×p is equivalent to p + p + p.
