Question

a:121+{76+55+[33-(18+16)-15-30}
b:77[16+(46-21)+8)
c:15+10+20-8+12-16
D: {165+[77-16+5-(17-6-3)]

Answer 1

A:
=121+{76+55+[33-(18+16)-15-30}
=121+{76+55+[33- 34 -15-30}
=121+{76+55 -46}
=121+ 85
= 206


b:77[16+(46-21)+8)
= 77 [ 16 + 25 + 8 ]
= 77 * 49
= 3.773

C:15+10+20-8+12-16
= 33

D: {165+[77-16+5-(17-6-3)]

= 165+[77-16+5- 8]
= 165+ 58
= 223
