Worksheet Worksheet 5
1.
In the same way that we used base-8 blocks to visualize addition in base-8, we can use it to help us perform subtraction.
Draw a blocks diagram to represent \(42_8 - 25_8\) and compute the result.
2.
Draw a blocks diagram to represent \(143_8 - 55_8\) and compute the result.
3.
Think about (but do not draw) the diagram you would need to represent \(52_8 - 33_8\) and compute the result from that mental picture.
