Trick to make appear a number four times

This trick is going to make a number you choose appear six times (to get the best effect it helps if you have a calculator). Think of a number between 1 and 9. Now multiply it by 7, then by 3, next by 11, then by 37, and finally by 13.




Example:


Let if i choose a no.4 then


4*7=28


28*3=84


84*11=924


924*37=34188


34188*13=444444 :-) 




also try this using C programing and C++ programming for your leisure time practices :-)
