Looking At The Number 143

In maths today we noticed that we could find lots of different ways of making the number 143 if we followed a pattern. Our first pattern was to add on to both numbers to get the same answer because it was take away. But our second pattern was addition so we had to do the opposite, if we went higher by 1 in one number we had to go lower by 1 in the other number. We found lots of ways to make 143.
