What is Multiplication?
Multiplication is one of the four basic arithmetic operations, along with addition, subtraction, and division. It represents repeated addition of the same number. For example, 3 × 4 means adding 3 together 4 times (3 + 3 + 3 + 3 = 12). Multiplication is fundamental to mathematics and has applications in everyday life, science, engineering, and finance.
Multiplication Properties
Commutative Property
The order of multiplication doesn't change the result: a × b = b × a
Associative Property
Grouping of numbers doesn't change the result: (a × b) × c = a × (b × c)
Distributive Property
Multiplication distributes over addition: a × (b + c) = (a × b) + (a × c)
Identity Property
Any number multiplied by 1 remains unchanged: a × 1 = a

Frequently Asked Questions
What is the difference between multiplicand and multiplier?
The multiplicand is the number being multiplied, and the multiplier is the number by which the multiplicand is multiplied. For example, in 5 × 3, 5 is the multiplicand and 3 is the multiplier.
How do I multiply decimal numbers?
Multiply decimal numbers as if they were whole numbers, then count the total decimal places in both factors and place the decimal point accordingly. For example, 2.5 × 3.2 = 8.00 (2+1=3 decimal places).
Can I multiply negative numbers?
Yes, multiplication with negative numbers follows specific rules: positive × positive = positive, positive × negative = negative, negative × positive = negative, and negative × negative = positive.
What is scientific notation in multiplication?
Scientific notation is used for very large or very small numbers. Multiply the coefficients and add the exponents. For example, (2.5 × 10³) × (4.0 × 10²) = 10.0 × 10⁵ = 1.0 × 10⁶.
