B clearly not, since 1+1=2, which is not in B
T clearly, since adding any two multiples of 4 yields another multiple of 4.
F yes, since adding any two integers yields another integer greater than 4.
No idea. What is W?
explain whether the following given are closed under addition:
B={0, 1}
T={0, 4, 8, 12, 16, ...}
F={5, 6, 7, 8, 9, 10,...}
{x|x E W and x>100}

the "E" is one of the weird looking e's for math. The "W" is in italics.
If 4 plus 5 equals 9 is the set closed under whole numbers and addition?
