u r making it so hard... any numbers divided by 25... just that that number multiply by 4 and move the decimal 2 places to the left... 92/25.. 79x4=316...answer is just 3.16.... 12345 divided by 25... just do 12345x4=49380 so answer is just 493.80

Now I can burn my calculator along with my Pepsi! As a fellow math nerd I appreciate this :] Perhaps as influential as the Pythagorean Therum or Quadratic Equation?! I think so, yes...

i know u can do it.. each person learned things differently so i just wanted to point out a different way of doing it. doing it my way, i can do with big numbers....because i know that any number multiply by 4 is just double the number and double again... when u do the 99/25.. still takes u a little big long to figure out the answer.. if you do 99x4... we know that 100x4 if just 400-4 is 396...so the answer is just 3.96..
