The basic multiplication formula is:

Product = First number × Second number

For example, if you multiply 15 by 25, the calculation is:

15 × 25 = 375

The calculator uses this simple formula to find the product of any two numbers you enter. The result is displayed in the result card below the calculator.

Worked examples

Example 1: Multiplying 15 by 25

Let's calculate 15 × 25 step by step:

  1. Multiply 15 by 20: 15 × 20 = 300
  2. Multiply 15 by 5: 15 × 5 = 75
  3. Add the two results together: 300 + 75 = 375

The final result is 375, which matches what the calculator shows.

Example 2: Multiplying 20 by 30

Let's calculate 20 × 30 step by step:

  1. Multiply 20 by 3: 20 × 3 = 60
  2. Multiply 20 by 10: 20 × 10 = 200
  3. Add the two results together: 60 + 200 = 260

The final result is 260, which the calculator will display if you enter 20 and 30.

FAQ

What is the difference between multiplication and addition?
Multiplication is repeated addition. For example, 3 × 4 means adding 3 four times (3 + 3 + 3 + 3 = 12). Addition simply combines two numbers (3 + 4 = 7).
Can I multiply negative numbers?
Yes, you can multiply negative numbers. The result will be positive if both numbers are negative, and negative if one number is negative and the other is positive. For example, -3 × -4 = 12, and -3 × 4 = -12.
What is the commutative property of multiplication?
The commutative property states that the order of multiplication does not affect the result. For example, 5 × 3 = 3 × 5 = 15.
How do I multiply decimals?
To multiply decimals, multiply the numbers as if they were whole numbers, then count the total number of decimal places in both numbers. Place the decimal point in the product so that it has the same number of decimal places.
What is the identity element of multiplication?
The identity element of multiplication is 1. Any number multiplied by 1 remains the same. For example, 7 × 1 = 7.
