Dividing Integers Practice Problems & Conceptual Mastery
Integer division is the inverse operation of multiplication. Because of this inverse relationship, the sign rules for division mirror those of multiplication exactly.
๐ Worked Step-by-Step Example
1. Check Signs: Negative รท Positive = Negative. 2. Divide Magnitudes: 72 รท 9 = 8. 3. Result: -8. 4. Check: (-8) ร 9 = -72 โ .
๐ง Core Problem-Solving Strategies
1. Same Sign: Positive Quotient
Dividing two integers with the same sign always produces a positive quotient.
2. Different Signs: Negative Quotient
Dividing two integers with opposite signs always produces a negative quotient.
3. Check via Multiplication
Always check quotient ร divisor = dividend.
๐ Key Mathematical Terms & Vocabulary
Dividend
The total number being divided (the numerator in a fraction).
Divisor
The number by which another number is divided (the denominator).
Quotient
The result obtained by dividing one quantity by another.
โ Frequently Asked Questions
What is negative divided by negative?
Negative divided by negative is always positive (e.g. -20 รท -4 = 5).
What is 0 divided by a negative number?
0 divided by any non-zero integer is 0 (0 รท -8 = 0).
Why is dividing by zero undefined?
No number multiplied by 0 can equal a non-zero dividend.
