Math problems?

Math problems?   Call 1-800-[(10x)(13i)^2]-[sin(xy)/2.362x].

In order for [(10x)(13i)^2)] to be between 100 and 999 inclusive, we need x to be between -16.9 and -1.691691692. But then the expression [sin(xy)/2.362x] has a maximum value of 0.250264293. Also, the last part must be a four digit integer ... it must be 0000, but real phone numbers don't use 0000 as the last four digits.

That is, assuming that sin(xy)/2.362x means sin(xy)/(2.362x). If it means x sin(xy) / 2.362, then the last four digits could also be 0000 to 0007.

And if we allow y to be a complex number, then the last four digits could be any four-digit integer.

That's what I read somewhere.
