80 - [ 130 - ( 12 - 4) 2 ]
= 80 - [ 130 - 82 ]
= 80 - [ 130 - 64 ]
= 80 - 66
= 14
\(80-\left[130-\left(12-5\right)^2\right]\)
\(=80-\left(130-8^2\right)\)
\(=80-\left(130-64\right)\)
\(=80-66\)
\(=14\)
\(80-\left[130-\left(12-4^2\right)\right]\)
=\(80-\left[130-\left(8^2\right)\right]\) \(=80-\left(130-64\right)\)
\(=80-66\)
\(=14\)
