10. You are asked to count the digits of the numbers in the elevation column of the table. The first number, -512, has three digits: -5, 1, and 2. The second number, -8327, has 4 digits: 8, 3, 2, and 7. You are asked to find the two numbers in the column that both have 4 digits. (Hint: -8327 is one of them.)
In the number -8,327, the digit in the thousands place is 8. (Hint: you read the number as "minus 8 thousand 3 hundred ...".) In the other 4-digit number, the digit in the thousands place is 1.
8 is greater than 1, so the number with the greater digit in the thousands place is -8327.
This number (-8327) is the elevation of the lowest place on Earth. The name of that place is found in the first column of the table where this number is in the second column. The name and number go into the last two blanks of problem 10.
