Placement of the Negative Sign in Division
Placement of the Negative Sign in Division is a Grade 7 math skill from enVision, Mathematics, Grade 7, covering Integers and Rational Numbers. For any integers and (with ): Explanation When a division results in a negative quotient, the negative sign can be placed in front of the entire expression, with the dividend (numerator), or with the divisor (denominator). This follows from the sign rules for division, as both a negative divided by a positive and a positive divided by a negative result in a negative answer.
Key Concepts
For any integers $a$ and $b$ (with $b \neq 0$): $$ \frac{a}{b} = \frac{ a}{b} = \frac{a}{ b}$$.
