How many palimdromic numbers is there between 300 and 400
2 answers:
A palindrome is something that reads the same forwards and backwards.
If the number is a palindrome and it's between 300 and 400, then the
last digit must also be a ' 3 '.
So all we have left to fill in is the digit in the middle.
There are 10 possibilities for that one ... the digits ' 0 ' through ' 9 '.
So there are <em>10</em> palindromic numbers between 300 and 400.
Palindromic is where if you flip the number around (123 would become 321) then it is the same so:
303
313
323
343
353
363
373
383
393
so there are 10
