Question

Mercury has a freezing point of -38. Water has a freezing point of 32. What is the difference

Answer 1

answer: 70

the difference just means subtraction.

so, let’s just subtract:

32-(-38)

a minus and a minus is a plus, so this becomes

32 + 38

which equals 70

another way you can do this is just by finding the absolute value (distance away from zero) of both the numbers and adding them. -38 is 38 away from zero, and 32 is 32 away from zero. so, just add the two to get 70. meaning that -38 is 70 away from 32

hope this helped! :)
