=+11+2 x [-2 + (-2)] 先計中括的 x ÷ 數
=+13 x [-2-2]
=+13 x - 4
=-52

第二部份錯左= 11 2 x -4 先折括號= 11 (-8) 先x÷後加減= 11-8=3
=+13 x [-2-2]
=+13 x - 4
=-52

(+11)-(-2) X [(+6)/(-3)+(-2)]
=(+11)-(-2) X[(-2)-2]
=(+11)-(-2)X(-4)
=(+11)-(+8)
=3
=(+11)-(-2) X[(-2)-2]
=(+11)-(-2)X(-4)
=(+11)-(+8)

=11 - [( -2) x ( -2 - 2 ) ]
= 11 - [( -2) x (-4)]
= 11 - (8)
=3
= 11 - [( -2) x (-4)]
= 11 - (8)
=3
