Solution :
We have to provide an expression for the binary numbers. There can be binary fractions or integers. Whenever there is leading 0, it is not allowed unless the integer part is a 0.
Thus the expression is :
![$(\in +.(0+1)^*(0+1))+(0.(0+1)^*(0+1))]$](https://tex.z-dn.net/?f=%24%28%5Cin%20%2B.%280%2B1%29%5E%2A%280%2B1%29%29%2B%280.%280%2B1%29%5E%2A%280%2B1%29%29%5D%24)
The best thing to do when an error message appears when it is not supposed to, as in if you are blocked by an administrator and it appears then its supposed to, it is best to contact someone who can investigate whether or not something is happening to your computer. That could be a parent, if they are good with computers, or just tech support at a store, provided they also know computers. Most of the time your computer just makes a mistake so nothing to worry about, but make sure to have it checked just to be sure.
