* Input the polynomial normally:
+ Change the operator quickly:
Ex: 123 press + and then press -×÷- Finally, the result is 123-
+ In addition, you can completely delete everything: operators, group (), etc and then continue inputting the polynomial normally. Calculator+++ Lite will help you calculate it accurately.
Ex: 123+4 press [Del] press [×] press [5] press [(] press [-] press [6]
result: 123×5×(-6
* Group:
You are always noticed the number of close group on App's screen and it doesn't seem to fulfill them later.
Ex: 13÷((5+1)-2×(3= means 13÷((5+1)-2×(3))=
Result: {Error, divide by Zero} Don't need close groups at the end.
* Separator:
Ex: (US) 12,345.6
(Vietnam) 12.345,6
* Repeating Rational:
If you see a number look like: 2.[3] it means: 2.333333333(3) charater 3 is being repeated nonstop.
Ex: 0.7÷3 = 0.2[3] and 2.[3]×3 = 7
* Testing:
You can input your polynomial like this
(((5+2)×3-(5)-2÷1))-3×(6)+3×(-5 = -19
0.003÷0.09 = 0.0[3]
