Why when you multiply by nine do the numerals in the answer add up to nine or several nines?

When you multiply a one- digit number by nine, then add up the digits, it does equal nine.
9x1= 9
9x2= 18 1+8=9
9x3= 27 2+7= 9
9x4= 36 3+6= 9
9x5= 45 4+5=9
ETC.
also, for the number you are multiplying by, the product's first digit will be one less than the number
