Why is the number zero so important in our math system? How would our math system be affected if there were no such thing as zero?

Step-by-step explanation:

The number zero is important because, For example, lets say it was 50+76

we NEED that zero else it would me 5+76 then, you woudn't get the right answer.

heyyy

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
