The computation of (TR)546 - (TR)540 will give a value of 3261.

How to compute the value?

TR(546)  =  546(546 + 1)/2  =  273 * 547

TR (540)  =  540(540 + 1)/2  =  270 * 541

273 * 547  = (270 + 3)(541 + 6)

= 270*541  + 270*6  + 541 *3  +  18

= 270*541  + 1620  + 1623  +  18

= 270*541  + 3261

TR(546) -TR (540)   = 270*541  + 3261  - 270 * 541

= 3261  

TR(546) -TR (540)   = 3261
