WEBAs in all subjects, it is important in mathematics that when a word is used, an exact meaning needs to be properly understood. This is where we will begin. When you were young an important skill was to be able to count your candy to make sure your sibling did not cheat you out of your share. These numbers can be listed: {1,2,3,4,...}.

WEBAlgebra Formulas. 1. Set identities. Definitions: I: Universal set A’: Complement. Empty set: ∅. Union of sets. A ∪ B = { x | x ∈ A or x ∈ B } Intersection of sets. A ∩ B = { x | x ∈ A and x ∈ B } Complement. A ′ = { x ∈ I | x ∈ A } Difference of sets. B \ A = { x | x ∈ B and x ∉ A } Cartesian product. × B = { ( x , y ) | x ∈ A and y ∈. }
WEBThe Discriminant. The discriminant is the part of the quadratic b2 equation under the radical, 4ac. We use the discriminant to determine the number of real solutions of ax2 + bx + c = 0 as such : 1. If b2. 4ac > 0, there are two real solutions.
