Formula Explained

When dividing two negative expressions, the following rules apply:

Division of Negative Expressions:

If both the numerator and denominator are negative, the negatives cancel out:

(-a) / (-b) = a / b

If only the numerator is negative:

(-a) / b = - (a / b)

If only the denominator is negative:

a / (-b) = - (a / b)

The calculator applies these rules to simplify the expression you provide.

Worked Examples

Example 1: Both Numerator and Denominator Negative

Divide (-6x²) by (-2x):

Remove the negative signs: 6x² / 2x
Simplify coefficients: 3x² / x
Simplify variables: 3x

Final result: 3x

Example 2: Only Numerator Negative

Divide (-9y³) by 3y:

Keep the negative sign: - (9y³ / 3y)
Simplify coefficients: - (3y³ / y)
Simplify variables: -3y²

Final result: -3y²

Example 3: Only Denominator Negative

Divide 12z by (-4z²):

Keep the negative sign: - (12z / 4z²)
Simplify coefficients: - (3 / z)

Final result: -3/z

Frequently Asked Questions

How do I handle negative signs when dividing expressions?

When both the numerator and denominator are negative, the negatives cancel out. If only one is negative, the result remains negative.

What if the denominator is zero?

Division by zero is undefined. The calculator will alert you if you attempt to divide by zero.

Can I simplify expressions with variables?

Yes, the calculator simplifies both numerical coefficients and variable terms.
