Basic Arithmetic assumptions
I disagree that "we created" the basic arithmetic operations (who is "we" anyway). These basic operations are natural operations that already existed before humans discovered and labelled them. Torkel1001 (discuss • contribs) 11:11, 13 February 2011 (UTC)

Reference to Number Line
I wouldn't assume that readers who don't know what addition and subtraction is understand the concept of a number line. I would prefer to explain this in terms of real world problems. Like you buy one apple and then another two apples, how many apples do you have? Torkel1001 (discuss • contribs) 11:11, 13 February 2011 (UTC)
