# Weights

##### Stage: 3 Challenge Level:

The largest total you can make is $20$ ($2A + 2C$).

The smallest total you can make is $-60$ ($2B + 2D$).

There are some totals that are easier to produce than others (perhaps those that require just one or two weights), so it may be a good idea to start with those and then build on them with a few extra weights.
