In this activity, we will add together pairs of square numbers from the list:
1, 4, 9, 16, 25, 36, 49, 64, 81, 100
Example How many different totals of two numbers can we find from the list : 1, 4, 9
Answer
Different totals that can be formed are:
1 + 4 = 5
1 + 9 = 10
4 + 9 = 13
That look fairly straightforward, doesn't it?
Let's have a go!
