Answer 1

Problem: what is the answer to 4+2[8+(3-1)]
at the end of the problem it should be squared

You don't need brackets. You can nest parentheses.

So, what you want is (4+2(8+(3-1)))^2

Start with the deepest nested parentheses and work outward.

(4 + 2(8 + (3 - 1)))^2
(4 + 2(8+ (2)))^2
(4 + 2(10))^2
(4 + 20)^2
(24)^2
