8. Root rules
• Radicand = number under sq root
• sq root (A*B)= sq r(A) * sq r(B)
• sq root (A/B) = sq root (A) / sq root (B)
9. real numbers
rational numbers
integers
whole numbers
natural (counting)
• real numbers = all
• rational numbers = fractions
• integers = -,0,+
• whole numbers 0,+
• natural (counting) 1,2,3
10. GCF, LCM
• GCF = Greatest common factor, that divides evenly into 2 (or more) numbers:
• 36 and 54 has following factors: 1, 2, 3, 6, 9, 18.
• 18 is GCF of 36 and 54

• LCM = smallest number that two numbers divide evenly
• Multiples of 5 = 10, 15, 20, 25, 30
• Multiples of 15 = 30, 45, 60
• 30 is LCM of 15 and 5
