The Grand Rapids Community College Mathematics Department is pleased to announce that it will host its October Mathematics Seminar today from 3-4 p.m. in 103 Cook.

This presentation will appeal to a wide range of students and faculty. Much of it requires no understanding of mathematics beyond arithmetic. All are welcome!

Pop and cookies will be served at 2:45 p.m.

Our speaker, GRCC Mathematics Instructor Andrea Hayes, will discuss division by zero in various forms of mathematics from basic arithmetic to higher-level mathematics. For the title and abstract of Andrea’s talk, please see below:

**Undefined**

Division by zero is often confusing and misinterpreted. Is (1/0) undefined or infinity? The answer often depends on who you ask and can lead to lively discussions, even arguments. The source of such discussions usually resides in the difference between actual division by 0 and what happens when the denominator approaches zero. This talk will provide an in-depth look at the complexity of division by zero at various levels of mathematics.
