A negative number is a number smaller than zero. This can be clearly seen on the number line below.
You will be asked to use your knowledge about negative numbers to solve different problems.
Example 1:
What is 6 minus 12?
You may be able to do this type of calculation in your head or it may help you to use a number line.
Answer:
This gives us -6
Example 2:
The temperature is -7°C in New York in January, it is 18°C warmer in Rome. What is the temperature in Rome?
Answer:
Count on from -7°C to 0 and then add on another 11 so in total, you have added 18.
This gives the answer 11°C
