Definition: Numbers are simply a set of symbols that represent quantity.

Two apples, five spoons, ten books, one hundred rubles, seven tulips. We use numbers every day, sometimes without even noticing it.

In early times, people represented the number of objects with sticks:

  • One item was represented as |
  • Two objects as | |
  • Three objects as | | |
  • Four objects as | | | |
  • Five objects as | | | | |

As literacy increased, people realized that sticks could not represent large numbers, so they replaced them with digits, which we still use today - 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Numbers often scare away schoolchildren and students because they are associated with "scary formulas" in mathematics. In fact, there's nothing scary about them. Numbers simply represent quantity or the number of items.

That's all there is to it. This introduction to numbers is complete. We will learn more about them in the future, but for now, this lesson is over.

I am attempting to do this with the hope that I'm able to encourage and help my children for learning mathematics. I hope that I'm able to come back and make a positive comment/experience of having gone through this

I’m getting my life together, and decided to go to college to pursue a business major in MIS. I am ashamed to admit that I was a horrible student in high school...

Thank you, Ken. I just did an assessment and did poorly and decided to search for anything that would help. Came across this website and your comment, I'm encouraged. Thank you.

I would put this quote as "Numbers are simply a set of symbols that are meant to represent quantity."

As used here, the word "numbers" and "number" wants to mean "digits/symbols" and "quantity of items"

I’m getting my life together, and decided to go to college to pursue a business major in MIS. I am ashamed to admit that I was a horrible student in high school, and graduated my senior year in geometry but did not retain any information from that class or the ones before. I am starting from scratch and will not give up. I’ve looked up books to buy but this website seems like it will be a big part of my progress, so thank you for creating this!

For a long time I was looking for something similar to this site. Other sites did not suit me because of the format of the video or rather complicated explanations. Here everything is simple and clear, thank you)
