## Start with values of b=0, c=0

## Start with values of b=0, c=0

## Change value of a to 1 (keeping b=0, c=0 and see what happens)

## Change value of a to 1 (keeping b=0, c=0 and see what happens)

## Change value of c to 1, 2, 3 etc  (keeping a=1, b=0 and see what happens)

## Change value of c to 1, 2, 3 etc  (keeping a=1, b=0 and see what happens)
