So, to add 4 and 4 in a standard equation, assuming you don't know that 8 is the correct solution, you must divide each 4 into quadrants. First, draw a circle around the top of the 4 to completely enclose the little box it has.

Want to check your work? If you draw a line connecting each numbered quadrant in the two 4s to the 8, you will find that each quadrant on the left side of the equal sign has a corresponding quadrant on the right side, proving your answer is correct!

Number the quadrants. Quadrants 1 and 2 belong on the inside of the 3's half-circles, just like in the circle of a 2, and then the extra space on the outside of the 3 gets its own third quadrant.

And because the number 9 contains a perfect circle, just like a 10, it deserves an Axis of 5 lines and 10 quadrants. Number them and count them up. Does it equal 9? No, because you have to subtract 1 from the useless stick dangling below the circle.
