This week, we had some strange temperatures! On Sunday the temperature was a chilly 2 degrees centigrade. By noon on Monday, it rose 18c. The temperature fell 7c by midnight, and another 2c at 4 am and then rose 11c by the time school began at 9 clock on Tuesday. This afternoon, Wednesday it rose another 5c. What was the final temperature? Show your equation.

Lets break this down by day and write what we would add/subtract to the temperature

Sunday: Temp was 2c

Noon Monday: it rose 18c so +18c

Midnight Monday: Fell 7c so -7c

4am Tuesday: Fell 2c so -2c

9 o'clock Tuesday: rose 11c to +11c

Wednesday afternoon: Rose 5c so +5c

Final temperature would be: 2c +18c -7c -2c +11c +5c = 27C
