    5. 5. LN 1: WHOLE NUMBERS AND MONEY VARIABLES AND EVALUATION Evaluate each expression for x = 10 and y = 5. x+y x-y xy x/y
    6. 6. PROPERTIES OF OPERATIONS Lesson 2
    7. 7. DID YOU KNOW..... All four mathematical operations are recorded in the Genesis 1-2 creation account. For example, God made a day and he divided it into evening and morning. He made one day; then He added something to it. He commanded animals to multiply upon the earth, adding numbers of “like things” to his creation. He subtracted a rib from Adam; then he added another human, Eve. http://www.christcentercurriculum.com/seminars/ what-makes-ccp-math-stand-out.php
