★ Be able to calculate some "informal expressions", for example:
normal expression ==> informal expression
0.2*0.4/0.5 ==> .2*.4/.5
50%*60%*70% ==> 50%60%70%
-((0.23%)%)% ==> -.23%%%
(-1.2)*(-3.4)*(-5.6) ==> -1.2*-3.4*-5.6
1%*sin(50%)*cos(30%)*(20%) ==> 1%sin50%cos30%20%
1.1*(-2+6.5)*(-7-1.1)*5.3 ==> 1.1(-2+6.5)(-7-1.1)5.3
8*(-4)*cos(-30.1)*tan(50.2) ==> 8*-4cos-30.1tan50.2
