Evaluate each expression:

18 - (7 - 7)

32 ÷ (8 - 4)

90 - 16 ÷ 4

3(18 - 12) - (5 - 3)

(24 - 10) - 3 × 3

4(22 - 18) - 3 × 5

12(5 - 5) + 3 × 5

18(4 - 3) ÷ 3 + 3

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
