Question

-(-6+4[2-5(4-3)(4-3)+2(7-3))]+2}-1=

Answer 1

-(-6+4[2-5(4-3)(4-3)+2(7-3))]+2}-1=

=−(−6+4(2−(5)(1)(4−3)+2(7−3)))+2−1

=−(−6+4(2−5(4−3)+2(7−3)))+2−1

=−(−6+4(2−(5)(1)+2(7−3)))+2−1

=−(−6+4(2−5+2(7−3)))+2−1

=−(−6+4(−3+2(7−3)))+2−1

=−(−6+4(−3+(2)(4)))+2−1

=−(−6+4(−3+8))+2−1

=−(−6+(4)(5))+2−1

=−(−6+20)+2−1

=−14+2−1

=−12−1

=−13

R// -13
