Multiply generally refers to the mathematical operation of multiplication, which is one of the four basic arithmetic operations (along with addition, subtraction, and division).Multiplication is essentially repeated addition.
Symbol: The most common symbols for multiplication are × , ⋅ , Parentheses . In algebra, simply placing numbers/variables next to each other implies multiplication

Commutative Property: a × b = b × a
Associative Property: ( a × b ) × c = a × ( b × c )
Distributive Property: a × ( b + c ) = ( a × b ) + ( a × c )
Identity Property: Any number multiplied by 1 remains unchanged.
Zero Property: Any number multiplied by 0 equals 0.

Whole Numbers: Basic arithmetic (e.g., 6×7=42).
Fractions: Multiply numerators and denominators .
Decimals: Multiply as whole numbers, then place the decimal .(e.g., 0.5×0.2=0.10).
Negative Numbers: Positive × Negative = Negative (e.g., 3×(−2)=−6) , Negative × Negative = Positive (e.g., −4×−5=20)
