Question

Re-write the statement 16 + 5/2-1 + 6 by including two pairs of brackets
to make the total value equal to 3.

Answer 1

These questions just take some trial and error. Try a bunch of things. After about 2 minutes I came up with

(16 + 5) / (2 - 1 + 6)

You can check this by simplifying everything inside the brackets.

21 / 7

= 3
