Adding and Subtracting Negative Numbers

This term we have been working on how to subtract and add negative numbers.  Watch this video which shows you how to do this and work out the answers to the questions below:-

1) -25 + 32 =

2) -136 + 42 =

3) 42 – 70 =

4) 139 -130 =

5) -450 + 423 =

6) 292 – 380 =

Remember if your number is positive you do not need to put a plus sign.  Have a go and see how many you can get right.
