Question

Insert parentheses in Expression 2 so that it has a value of 19. Then show why your expression has a value of 19.

Expression 2:
5+4^2+6-2^2-1

Answer 1

Explanation:

(5+4)x2+6-2x2-1=19

Answer 2

I am thinking there might be an error in the equation or the value being because no matter where I place the parentheses it will have the same value of 22. The expression will always simplify to 22. Please feel free to ask more questions in the future.
