Answer 1

32+63×31-123
=(32-1)+63x31+(-123-1)+2
=(31+63x31-124)+2
【括号内提取31】
=31x(1+63-4)+2
=31x60+2
=1862

Answer 2

Answer 3

解，32+63×31-123

=31+1+63*31-31*4+1

=31*(1+63-4)+2

=31*60+2

=1862

Answer 4

32+63×31-123
=63×31-（123-32）
=63×31-91
=63×（30+1）-91

这样计算就简便一点

Answer 5

提取公因式，所以
原式=(31+1)+31×63-(31×4-1)
=31+1+31×63-31×4+1
=31+31×63-31×4+2
=31×(1+63-4)+2
=31×60+2
=1860+2
=1862
