Example Question #1 : Understanding Addition And Subtraction
Use the triangles below to help you answer the subtraction problem.
We have triangles and we want to subtract triangle, which means the same thing as take them away. We can cross off the triangle that we are subtracting, and count the number that we have left. In this case we have triangles left. Subtraction is like counting backwards. We can start at and count back .
