I am trying to do (7*(7-6+2)^2)-6.
I get 435.
The calculator says 57.
(7*(7-6+2)^2)-6=7*(1+2)^2-6=7*3^2-6=7*9-6=63-6=57
(7*(7-6+2)^2)-6 = [ perform all the operations in the innermost parentheses, first ]
(7*(1 + 2)^2) - 6 =
(7* (3)^2) - 6 = [ evaluate the exponent ]
(7 * 9) - 6 = [multiply within the parentheses ]
63 - 6 =
57
