我输入我再Mathematica运行的结果.其中,“In[]：=”是Mathematica自动显示的.你输入时不要输入,只输入下面一行的东西就是了.
问题1
In[1]:=
a=3;b=4;c=5;
(a+b)(b+c)
Out[2]=
63
问题2
In[3]:=
N[E,25]
Out[3]=
2.718281828459045235360287
问题3
In[4]:=
12*6
Out[4]=
72
In[5]:=
15*7
Out[5]=
105
In[6]:=
%+%%
Out[6]=
177
问题4：
In[7]:=
Factorial
运行后会显示,
"n!gives the factorial of n.More..."
In[8]:=
Factorial
运行后会显示,
"n!gives the factorial of n.More..."
Attributes[Factorial]={Listable,NumericFunction,Protected}
In[9]:=
Factorial[100]
Out[9]=
933262154439441526816992388562667004907159682643816214685929638952175999932299

00
问题5
In[10]:=
Table[Random[Integer,{1,6}],{i,1,4}]
Out[10]=
{4,4,3,2}
每次运行结果会各不相同.
也可以写个小循环,
In[13]:=
For[i=1,i
