So…what is multiplication? Repeated addition! 40 + 40 + 40 = 120 40 x 3 = 120
MULTIPLICATION OR DIVISION DO the multiplication or division. Determine the sign:
Look in your math toolkit! If you ever forget…
Practice! • -3 x -9 = • -14 / 2 = • -16 / -8 = • -4 x 10 = • 30 / -5 =
STUDY! Practice problems that I STRONGLY suggest you look at!! Pg 99: problems 1-9 AND problems 15-26
