a) -150+ [{(-24) - 50- (-10 + 16 x 2-17)} +120]
b) 18+ (-15+3 of {-51+ 3 +62 - -5x5}]
c) 125-1-20 of (-16) + {15 - (-5)}]
-120 + (-45 - {15 - 10% (-18 - 15)}]
5. Check whether the simplification of the expressions is
a) 130 + 5% (-6) + 75 - {50 * 2-(40 - 5)} is equal
4000 - {20 of (-5)} - 63+ [63-(-45) - 15] is eq
