Sorry Drakkar for that out of subject intervention:
Last intervention regarding the way to write numbers, because it's not a Quebec thing, but an internationnal thing. Wikipedia is quite interesting on the subject. Let's just say that the trend is to go without commas to separate the thousands. Like it is to use cm and kilometers even if we all use both metric and imperial units of measure around here.

Just an extract to understand better:

The 22nd General Conference on Weights and Measures declared in 2003 that "the symbol for the decimal marker shall be either the point on the line or the comma on the line". It further reaffirmed that "numbers may be divided in groups of three in order to facilitate reading; neither dots nor commas are ever inserted in the spaces between groups".[10] This usage has therefore been recommended by technical organizations, such as the United States' National Institute of Standards and Technology.

The convention for digit group separators varies but usually seeks to distinguish the delimiter from the decimal mark. Typically, English-speaking countries employ commas as the delimiter—10,000—and other European countries employ periods or spaces: 10.000 or 10 000. Because of the confusion that can result in international documents, the withdrawn SI/ISO 31-0 standard advocates the use of spaces[12] and the International Bureau of Weights and Measures and International Union of Pure and Applied Chemistry advocate the use of a "thin space" in "groups of three".[13][14] Within the United States, the American Medical Association's widely-followed AMA Manual of Style also calls for a thin space.[11

And to finish, I went to check an excerpt from the Ontario math program, and noticed that the way they write numbers is 10 000 and not 10,000 but with the use of the period for decimals. So it makes all of us learning about the same thing.
