How to find temperature differences
To find the difference between two positive temperatures, you just take the smaller one away from the largr one.
The difference between 7 and 12 is 12 - 7 = 5
To find the difference between two negative temperatures, you just add them together, remembering that + - is the same as - .
The difference between -7 and -12 is -7 + (-12) = -7 - 12 = -19
To find the difference between a positive and a negative temperature, you need to count down to 0 and then carry on counting downwards until you reach the number that you require.
So the difference between 6 and -8 is from 6 to 0 is 6 and then from 0 to -8 is another 8 which means the difference between the two numbers is 6 + 8 = 14
