What you've learned

You finished Equality and identities. These are always true:

• Reflexive property A = A
• Transitive property If A = B and B = C, then A = C
• Symmetric property If A = B, then B = A
• Commutative property of addition A + B = B + A
• Additive identity A + 0 = A
• Multiplicative identity 1A = A
• Zero property of multiplication 0A = 0
