Regulations: If A is greater than B, then ︳AB︳=AB; if A is equal to B, then ︳AB︳=0; if A is less than B, then |AB︳=BA. Calculate according to the above rules:|2013-2014︳+︳2014-2013︳+︳2014-2014︳=How much.
规定：如果A大于B，则︳A-B︳=A-B；如果A等于B，则︳A-B︳=0；如果A小于B，则|A-B︳=B-A．根据上述规律计算：|2013-2014︳+︳2014-2013︳+︳2014-2014︳=多少．
