2. 25 (42 + 2 3 ) 25 (42 + 8) 25 (50) 2 4.

3. 5 + 4 2 - 3 (7) + 3 2 5 + 16 – 3(7) + 9 5 + 16 -21 + 9 21 – 30 - 9

4. t = 2 and u = 1 4 t + 2u 2 – u 3 4 2 + 2 1 2 – 1 3 8 + 2 2 – 1 8 + 4 – 1 12 – 1 11

5. a = -2 and b = 3 (2a) 2 - (b 3 - a 2 ) (2 - 2) 2 - (3 3 - 2 2 ) - 4 2 - (27 - 4) - 16 – 23 - 39

6. p= 2 and q = 5 qp +(p)(5 - p)+p 6 5 2 + (2)(5 – 2) + 2 10 + (2)(3) + 2 10 + 6 + 2 18

7. 25 (42 + 2 3 ) 25 (42 + 8) 25 (50) 2 4. Little divided by big is a fraction!!!! Divide left to right!!!

8. 5 + 4 2 - 3 (7) + 3 2 5 + 16 – 3(7) + 9 5 + 16 -21 + 9 21 – 30 - 9 Add and subtract LEFT to RIGHT!!!

9. t = 2 and u = 1 4 t + 2u 2 – u 3 4 2 + 2 1 2 – 1 3 8 + 2 2 – 1 8 + 4 – 1 12 – 1 11 Watch what is being squared!!!!

10. a = -2 and b = 3 (2a) 2 - (b 3 - a 2 ) (2 - 2) 2 - (3 3 - 2 2 ) - 4 2 - (27 - 4) - 16 – 23 - 39 Use parenthesis when squaring a negative…a negative squared is always positive!!!
