Answer 2

305-[86+(3×5-2)]= 305-[86+(10-2)]= 305-[86+8]=305-94==> 211
=====================================================
118+{15-[4+(8÷4-1)]}= 118+{15-[4+(2-1)]}= 118+{15-[4+1]}=

118+{15-5}= 118 + 10 ==> 128
=====================================================
276÷2+(5×7×6-39)= 138+(210-39)= 138+171 = 309
=====================================================
802÷2+[64÷2+(5×3-10)]= 401+[32+(15-10)]= 401+[32+5]= 401+37 = 438
=======================================================
10×3+2-(8×8-52)= 30+2-(64-52)= 32-12 = 20
=======================================================
650÷2+(3×7-11)= 325 + (21-11) = 325 + 10 = 335
======================================================
15÷3×2+(7×4-20)= 5×2+(28-20)= 10+8 = 18
======================================================
438÷2+5+5(6×8-42)= 219+5+5(48-42)=219+5+5(6)= 224+30=254
