Multiplying Integers Calculator is a free online tool that displays the product of two integers. Multiplying integers calculator can be used to multiply any two positive or negative integers instantly. The integers are whole numbers including 0, positive number and negative numbers. The fractions, decimals, and percents do not fall under the integers category.

How to Use Integers Multiplication Calculator?

In the integer multiplication calculator tool, there are two input boxes and a multiplication sign in the middle. To multiply any two integers, follow the steps given below.

  • Step 1: Enter any integer in the first input box.
  • Step 2: Enter another integer in the second input box.
  • Step 3: Click on “Solve” to compute the value of the integers.

How to Multiply Integers?

It is known that integers can be positive or negative. To multiply integers, their signs should always be taken into account. The resultant sign for multiplying different polynomials is given in the following table.

Rules to Multiply Integers:

Type of Integer Resultant Sign Example
2 Positive Integers Positive a × b = ab
2 Negative Integers Negative Sign – a × – b = – ab
1 Positive and 1 Negative Integer Negative Sign – a × b = – ab

Or,

a × – b = – ab

Solved Examples

Example 1:

Simplify -4 × 20

Solution:

Given that, -4 × 20

In this case, the first integer has a negative sign and the second integer has a positive sign, hence the result should be negative.

-4 × 20 = -80

Example 2:

Simplify -20 × -50

Solution:

Given:  -20 × -50

Here, two given integers are negative, hence the multiplication of two negative integers will result in a positive integer.

Therefore, -20 × -50 = 1000
