  18. Order of Math Operations • 6 X 8 + 2 = 50 ???? or 6 X 8 + 2 = 60 ???? (6 X 8) + 2 = 50 6 X (8 + 2) = 60 • NOT operations are performed first • AND operations are evaluated next • OR are completed last. • Math anxiety AND girls NOT boys • Math anxiety AND (girls NOT boys)

  19. Order of Math Operations • 6 X 8 + 2 = 50 ???? or 6 X 8 + 2 = 60 ???? (6 X 8) + 2 = 50 6 X (8 + 2) = 60 • NOT operations are performed first • AND operations are evaluated next • OR are completed last. • Math anxiety AND girls NOT boys • Math anxiety AND (girls NOT boys)

  20. Order of Math Operations • 6 X 8 + 2 = 50 ???? or 6 X 8 + 2 = 60 ???? (6 X 8) + 2 = 50 6 X (8 + 2) = 60 • NOT operations are performed first • AND operations are evaluated next • OR are completed last. • Math anxiety AND girls NOT boys • Math anxiety AND (girls NOT boys)

  21. Order of Math Operations • 6 X 8 + 2 = 50 ???? or 6 X 8 + 2 = 60 ???? (6 X 8) + 2 = 50 6 X (8 + 2) = 60 • NOT operations are performed first • AND operations are evaluated next • OR are completed last. • Math anxiety AND girls NOT boys • Math anxiety AND (girls NOT boys)
