have tryed solve an easy equation and got "NoRealRoots"

after simple the equation as "x+23=0"  the error the same.

you can solve it by using either roots() or solve()

However if you use the (2) arguments version, the result domain is the one set in your program settings: Tools > Options > Calculation > Roots (range)

This is by default set between -20 and 20, hence the error (no roots in that domain); also, because each user might have different settings, these (2) arguments functions are probably better used as on-the-fly tools.

If you want environment-indipendant  results I suggest you to use the (4) arguments alternative, where limits are explicit.
