Multiplication and Division of Negative Numbers

When multiplying negative numbers, if the signs are the same, the answer is positive; if the signs are different, the answer is negative.

When dividing negative numbers, if the signs are the same, the answer is positive; if the signs are different, the answer is negative.

Multiplying -12 by -4 results in a positive number 48 because the signs are the same.

Dividing 63 by -7 gives -9 because the signs are different.

To find the sign of a multiplication result you need to assess the sign of the integers

To find the sign of a division result you need to assess the sign of the integers

Negative numbers are used in algebraic expressions and must be treated properly during simplification.

The order of operations (PEMDAS/BODMAS) dictates how mathematical operations are performed in expressions with multiple calculations.

When a negative number is raised to a power, apply the exponent to the absolute value of the number, then retain the positive sign.
