2) a. -62 is less than (colder than) -55 so the average temperature on Mars is warmer.
b. -62 < -55
3) No. -14 means that the number is 14 <u>less than</u> zero. -21 means that the number is 21 <u>less than</u> zero. Also, if you plot these numbers on a number line, -21 will be further to the left than -14. The further to the left a number is, the less it is. So, -21 is less than -14 and Anchorage is colder than Minneapolis.
