Answer 1

To find out how far away 10 and -11 are from each other on a number line (or thermometer), you subtract the smaller number from the larger number.

The calculation is:

\[ 10 - (-11) = 10 + 11 = 21 \]

So, 10 and -11 are 21 spaces apart on the number line.

The correct answer is 21 spaces.
