Find the change in temperature from 23 degrees to 65 degrees. Use an integer to represent the change.

Our first thermometer reads 23 degrees. Our second reading tells us 65 degrees. We started at 23 and then increased to 65. What integer could represent this change? First, we need to do some subtraction to find out how much is between 23 and 65.

Five minus three is two. Six minus two is four. There is an increase of 42 degrees here. Because the change in temperature is positive, it’s going up, we would use a positive 42 to represent this change.

Positive 42 is the integer that represents the change in temperature from 23 degrees to 65 degrees.
