$(12-5^2-:5)*4^2-:2^3+2^2-1+[(2^4-:2^3)^3+4^3-:4+2^5]-:7=25$

$(12-5^2-:5)*4^2-:2^3+2^2-1+[(2^4-:2^3)^3+4^3-:4+2^5]-:7$

= $(12-25-:5)*4^2-:2^3+2^2-1+[(2)^3+4^2+2^5]-:7$

= $(12-5)*(2^2)^2-:2^3+2^2-1+[8+16+32]-:7$

= $7*2^4-:2^3+2^2-1+56-:7$

= $7*2+4-1+8$

= $14+4-1+8$

= $25$

Simplify: (12−5^2-:5)*4^2-:2^3+2^2−1+[(2^4-:2^3)^3+4^3-:4+2^5]-:7(12−5^2-:5)*4^2-:2^3+2^2−1+[(2^4-:2^3)^3+4^3-:4+2^5]-:7?
