Use 3 of these cards to create a total of 15. (For example 1 + 5 + 9 = 15)
Easy?
How many different ways can you do this?

It was hard but I got it in the end. At first I put loads of the same numbers like ……….1+1+1+1+1+1+1+1+1+1+1+1+1+1+1=15.
Wow Olivia. I’d only considered using addition to find a total. Great work in making use of multiplication and subtraction.
