Answer:
The description provides the clues for each digit in a 6-digit number. Let's break it down:
1. Highest place value and lowest place value has a number equals to the number of days in a week: There are 7 days in a week, so the first and last digits are 7.
2. Hundreds place is equal to half a dozen: Half a dozen is 6, so the third digit from the right (hundreds place) is 6.
3. Tens place is the number of sides of a triangle: A triangle has 3 sides, so the second digit from the right (tens place) is 3.
4. Thousands place is equal to the number of poles of earth: Earth has two poles, so the second digit from the left (thousands place) is 2.
5. Ten thousands place is equal to result of subtracting any number from itself: Subtracting any number from itself yields 0, so the third digit from the left (ten thousands place) is 0.
Putting it all together, the 6-digit number would be: 702,637.
