Thank you to faculty member Swati Juthani for pointing out the differences in number conventions between Canadian and Indian English. Your students from India may be making mental adjustments for the first while when listening to or reading the higher numbers.
Here is a chart that Swati and I put together. I wrote a list of English numbers, and Swati showed what the equivalent would be in Indian English.
|Canadian English convention||Indian English convention|
|Notation||1 through 100||Same|
|Terminology||One through one hundred||Same|
|Terminology|| Two thousand, five hundred |
| Two thousand, five hundred only. |
Another one is not used
|Terminology||One hundred thousand||One lakh|
