Rules for Dividing Signed Numbers

1. The quotient of two numbers with the same sign is positive. 2. The quotient of two numbers with opposite signs is negative. 3. Zero divided by any number (except zero) is zero. 4. The quotient of any number divided by zero is undefined. Division is the inverse of multiplication, so its sign rules are the same. Since 3 \times (-4) = -12, it follows that -12 \div (-4) = 3. Division by zero is undefined because no number can multiply by zero to get a non-zero result. This skill is part of Grade 8 math in Yoshiwara Core Math.

Key Concepts

Property 1. The quotient of two numbers with the same sign is positive. 2. The quotient of two numbers with opposite signs is negative. 3. Zero divided by any number (except zero) is zero. 4. The quotient of any number divided by zero is undefined.

Examples The quotient of two numbers with opposite signs is negative: $32 \div ( 8) = 4$. The quotient of two numbers with the same sign is positive: $\frac{ 45}{ 9} = 5$. Division by zero is undefined, but zero divided by a non zero number is zero: $\frac{ 14}{0}$ is undefined, while $\frac{0}{7} = 0$.

Explanation Division is the inverse of multiplication, so its sign rules are the same. Since $3 \times ( 4) = 12$, it follows that $ 12 \div ( 4) = 3$. Division by zero is undefined because no number can multiply by zero to get a non zero result.
