8. The Order of Operations BEDMAS

9. The Order of Operations BEDMAS B E DM AS

10. The Order of Operations BEDMAS B- Do operations in brackets first. E DM AS

11. The Order of Operations BEDMAS B- Do operations in brackets first. E- Evaluate exponents next. DM AS

12. The Order of Operations BEDMAS B- Do operations in brackets first. E- Evaluate exponents next. DM- Do dividing and multiplying in the order they appear. AS

13. The Order of Operations BEDMAS B- Do operations in brackets first. E- Evaluate exponents next. DM- Do dividing and multiplying in the order they appear. AS- Do adding and subtracting in the order they appear.

14. The Order of Operations BEDMAS Ex) 5 x 6 – 4 ÷ 2 = 30 – 2 = 28

15. The Order of Operations BEDMAS Ex) 4 x 12 ÷ 3 x 2 – (9 + 4) = 4 x 12 ÷ 3 x 2 – 13 = 48 ÷ 3 x 2 – 13 = 16 x 2 – 13 = 32 – 13 = 19

16. The Order of Operations BEDMAS Ex) (4 + 3 2 – 2 3 ) 2

17. The Order of Operations BEDMAS Ex) (4 + 3 2 – 2 3 ) 2 = (4 + 3x3 – 2x2x2) 2

18. The Order of Operations BEDMAS Ex) (4 + 3 2 – 2 3 ) 2 = (4 + 3x3 – 2x2x2) 2 = (4 + 9 – 8) 2

19. The Order of Operations BEDMAS Ex) (4 + 3 2 – 2 3 ) 2 = (4 + 3x3 – 2x2x2) 2 = (4 + 9 – 8) 2 = 5 2

20. The Order of Operations BEDMAS Ex) (4 + 3 2 – 2 3 ) 2 = (4 + 3x3 – 2x2x2) 2 = (4 + 9 – 8) 2 = 5 2 = 25
