Try it with some random number, like a=3.
Is "3+0 = 0+3 = 0" true? No.
If you were doing multiplication, then it would be true, but not with addition.
Nothing really, it is in my genetics that i have a middle toe longer than my big toe. My friend doesn't have the genetics and his middle toe is not as long as his big toe. It is all in genetics.
I hope this helps you
