Rules for Multiplication of Signed Numbers

When multiplying integers, if the numbers have different signs, the product is negative, and if they have the same sign, the product is positive. This rule ensures consistency in the behavior of arithmetic operations involving negative numbers.

Multiplication

Multiplication is a basic arithmetic operation that represents repeated addition of a number. It is one of the four fundamental operations in mathematics and is used to scale or increase quantities.

Integers

Integers include all whole numbers as well as their negatives and zero. They form a number system where arithmetic operations, such as multiplication, follow specific rules that extend beyond positive numbers.
