Question

How can we show a number increased by 2? Can you prove this using a model? If so, draw the model.

Answer 1

x + 2

Explanation:

Let x be the unknown number,

For making the diagram to model this problem,

Take a grid that shows x, ( shown below )

Then take a grid that shows 2.

Join these grids,

We obtain a grid, showing x + 2

Hence, the required expression that represents the given situation is x + 2
