Zero Property of Multiplication and Division
Zero Property of Multiplication and Division is a Grade 3 math skill from Eureka Math covering how zero behaves in multiplication and division. Any number multiplied by zero equals zero (n × 0 = 0). Zero divided by any nonzero number also equals zero (0 ÷ n = 0). These rules hold in both directions of multiplication and apply consistently across all numbers. Third graders learn these as quick-recall facts that simplify computation and lay groundwork for algebraic properties studied in later grades.
Key Concepts
The Zero Property of Multiplication states that any number multiplied by 0 is 0. When dividing, 0 divided by any non zero number is also 0. $$n \times 0 = 0$$ $$0 \div n = 0 \text{ (for } n \neq 0\text{)}$$.
Common Questions
What is the zero property of multiplication?
Any number multiplied by zero equals zero. For example, 7 × 0 = 0 and 0 × 54 = 0. This applies to all real numbers.
What happens when you divide zero by a number?
Zero divided by any nonzero number equals zero. For example, 0 ÷ 5 = 0 and 0 ÷ 100 = 0.
Why does any number times zero equal zero?
Multiplication counts equal groups. Zero groups of any size—or any number of groups with zero in each—always totals zero.
Does the zero property apply to both orders of multiplication?
Yes. Because of the commutative property, n × 0 = 0 and 0 × n = 0 are both true.
In which textbook is the Zero Property of Multiplication and Division taught?
This skill is taught in Eureka Math, Grade 3.
