When you do a Riemann's sum, you split the interval into columns. In choice 3 we are told that there are 4 equal subdivisions meaning that each of the 4 columns are 1 wide. Since it is a left Riemann's sum we add the height of the column where the LEFT side crosses the curve. For [-1, 0], the height is -1, for [0, 1] it is 0, for [1, 2] it is 2, and for [2, 3] it is 3. Now add the heights together to get 4. Then you multiply by the width, but since the columns are 1 wide, the answer is still just 4.

Balancing equations makes sure that the numbers of atoms of an element on one side of the equation are the same as those in the other side. This ensures that the law of conservation of matter is observed because matter cannot be destroyed or created in chemical reactions – therefore the mass of reactants must be the same as those of the products.
