Explanation : when multiplying 10 with 4,000 we get
4000 X 10 = 40,000.
As we multiply, using the chart there are 4 thousand present in the row of thousand column. When we multiply that with 10 it gets shifted to left and becomes 40,000.
This would be true because it shows that p equals either a or b and it also shows that p equals a which is true because it is one of the independent choices.
