Maths Question

As part of our thinking work (see – http://head.leverhouse.net/2016/12/05/thinking-board/) our KS 2 children have been working on a Maths puzzle – using all the digits – 1, 2, 3, 4, 5, 6, 7, 8, and 9 IN ORDER and then adding only + or – can you get a total of 100.

Here are some early puzzle breakers:

123 + 45 − 67 + 8 − 9 = 100

 

 

 

 

 

 

There is also –1 + 2 + 3 — 4 + 5 + 6 + 78 + 9 = 100

Can you find anymore?

What is the largest number you can make?

What is the smallest positive number you can make? Can you make 1?
