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.
