Answer 2

Multiplying Integers with Different Signs

When multiplying two integers with different signs, you need to multiply the absolute values of the numbers and then assign the product a negative sign. Here's how it works:

To multiply two integers with different signs: - Multiply the absolute values of the numbers. - Assign the product a negative sign.

For example, when multiplying 2 and -6: - |2| = 2 - |-6| = 6 - 2 * 6 = 12 - Since the original numbers have different signs, the result is -12.

This can be represented as: 2 * (-6) = -12.

Multiplying Two Negative Integers

When multiplying two negative integers, you simply multiply the absolute values of the numbers and the result is positive. Here's the process:

To multiply two negative integers: - Multiply the absolute values of the numbers. - The result is positive.

For example, when multiplying -5 and -2: - |-5| = 5 - |-2| = 2 - 5 * 2 = 10

This can be represented as: (-5) * (-2) = 10.

In summary, when multiplying integers with different signs, the result is negative, and when multiplying two negative integers, the result is positive.
