=32-[48÷{36-(27-25) } ]
=32-[48÷{36-2} ]
=32-[48÷34]
=32-

4834

=32-

(1) 8+4÷2×5
=8+2×5
=8+10
=18

(2) 54÷3 of 6+9
=18 of 6+9
=108+9
=117

(3) 13-(12-6÷3)
=13-(12-2)
=13-10
=3

(4) 1001÷11 of 13
=91 of 13
=1183

(5) 133+28÷7-8×2
=133+4-16
=137-16
=121

(6) 3640-14÷7×2
=3640-2×2
=3640-4
=3636

(7) 100×10-100+2000÷100
=1000-100+20
=1000-80
=920

(8) 27-[18-{16-(5-(4-1) ̅ ) } ]
=27-[18-{16-(5-5) } ]
=27-[18-{16-0} ]
=27-[18-16]
=27-2
=25

(10) 8-[28÷{34-(36-18÷9×8) } ]
=8-[28÷{34-(36-2×8) } ]
=8-[28÷{34-(36-16) } ]
=8-[28÷{34-20} ]
=8-[28÷14]
=8-2
=6
