Come on now, Tayala !

What if I say to you:
"Start with 3 cows, take away 7 cows, and then add 14 cows. How many are there ?"

Don't let the little 't' scare you.  It doesn't matter one bit what 't' really is.  It can be
a number, a teacher, a tiger, or a teacup.  Whatever it is, you start with 3 of them,
take away 7 of them, and then add on 14 of them.  How many are there ?

Hint:  If there are not ten of them, then go back and look at the cows again.
