Question

Answer 1

\(b,35-\left\{12-\left[-14+\left(-2\right)\right]\right\}\\ =35-\left\{12-\left(-16\right)\right\}\\ =35-28\\ =7\)

Answer 2

\(35-\left\{12-\left[-14+\left(-2\right)\right]\right\}\)
\(=35-\left(12+14+2\right)\)
\(=35-28=7\)

Answer 3

 

35−{12−[−14+(−2)]}=35−{12−(−16)}=35−28=7

Answer 4

=35 -{12-[-(14+12)]

=35-{12-(-16)}

=35-28

=7
