$\displaystyle a>b \mbox{ and }c>d\mbox{ then }a+c>b+d$Originally Posted by idaliaa
There exist such a number 0 such as,Identity Property Addition
$\displaystyle x+0=0+x=x$ for any real x
For any $\displaystyle x,y,z$ that are real you have,Grouping Property Addition? Thanks.
$\displaystyle (x+y)+z=x+(y+z)$
