Number line addition

This task is about showing how to solve addition equations on a number line.
For the questions below:
  1. Show how to solve the equations on the number line.
  2. Write the answer in the empty box.
Read the example below before you start.
 
Example: For the equation: 8 + = 30, Maraea used tidy numbers to show the answer on a number line.

She knew that 8 + 2 = 10, and 10 + 20 = 30.
So she showed this on the number line and wrote the answer in the box:

 8 + = 30.
