I have a maximum/minimum thermometer in my greenhouse. It records the highest and lowest temperatures reached since the time I reset it.
I reset it on Sunday when the temperature was 4° C.
Overnight the temperature fell by 5°.
Then during Monday it rose by 6° before falling by 10° during the night.
On Tuesday it rose by 4° and fell by 2° overnight.
What were the maximum and minimum temperatures recorded when I looked at the thermometer on Wednesday morning?
