We have had great fun with our maths learning this week, especially when looking at negative numbers. We wrote on tables in order to play a game to help us understand what happens when calculating with positive and negative numbers.
We found out:
If you + a positive number (++) the value will increase.
If you - a positive number (-+) the value will decrease.
If you + a negative number (+-) the value will decrease.
If you - and negative number (--) the value will increase.
