What happens when you add 7 to a number?
Likewise adding 7 to a digit reduces it by 3 and adds 1 to the digit in the next place, a net reduction in the sum of digits of 2. Thus when 7 is added to 7 the sum of digits is reduced to 5. When 7 is added to 5 the sum of digits is reduced to 3. When 7 is added to 3 the sum of digits is reduced to 1.
What makes a two digit number an even number?
Two digit numbers where the ten�s digit is greater than the one�s digit implies exactly 2 digits. Four more than each number is a multiple of 6 means even numbers, because an odd number plus 4 would still be odd and could not be a multiple of 6. So the ones number could be 0, 2, 4, 6, or 8.
