Start at 5/6 on the number line. Move 11/6 spaces to the left (11/6 is negative; if you are adding a negative number, move to the left). You should land on -1.
If x is an odd number, then the next odd number will be : x + 2
30, once a month, twelve months in a year times 2 you get twenty four plus the other six for the extra half year
Angle 3 is 96 degrees - angles on a straight line add up to 180 degrees
Hope this helps!
