Not yet answered if all digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are rotated through a 180°, the digits 0, 1, and 8 do not change meaning, the digit 6 becomes 9, and 9 becomes 6. the remaining digits lose their meaning. a palidium is a positive whole number that remains the same after a 180° rotation (for example, 1691 or 8008). how many numbers between 1000 and (inclusive) are palidiums? marked out of 4 p flag question
