#1, U = union, list all numbers that are seen in B or C

B = {2, 4, 6}
U
C = {1, 3, 5}

All numbers in B or C
{1,2,3,4,5,6}

Answer 3

ill do one of the upside down U's too

#2) A AND B

A = {1, 2, 3, 4, 5}
B = {2, 4, 6}

What is seen in A AND B
{2,4}

Answer 4

that is all the U and upside down U things mean

Answer 5

A ∩ (B ∩ C)

for those, first do the parenthesis, A AND B, then do A AND (the set from the first A AND B)
