Think? – pt.3

Numbers: My basic counting image is a continuous line with abrupt 90 degree turns (like some of my other images).
Fig. 7 - How I see Numbers
The dotted path about (300) is only for horsepower and cubic inches. It then resumes the normal path.
When I think of a calue, I always place it along the line in Fig.7. Here are examples of some values that I place on this line...
Note: I picture an equal distance between all numbers. This illustration shows direction and shape but the scale is actually much larger.
Math: Have you ever wondered how you actually add or subtract numbers? - not strict memorization - which I rarely use. It was interesting to see how many actual steps my mind goes through when adding or subtracting. Other people might do the same type of thing. I would be curious to see how others add and subtract. How do I add or subtract? I use compliments (base 10) - that is I compare everything to 10 and then combine the pieces to get my answer. This process was very difficult to illustrate. I attempted to outline it below, but I may have just confused the issue.

How I calculate 8 + 14:

  1. Subtract 4 from 10 = 6.
  2. Take the 6 and subtract it from 8 = 2.
  3. Add 10 to the first digit in 14 which is 1 = 20
  4. Take the result from step 2 (2) and add to the result from step 3 (20) - that gives me 22 ! All that for a little addition!

How I calculate 14 - 8:

  1. Subtract 10 from 14 which gives the ones digit of 14 = 4.
  2. Subtract the result from step 1 (4) from 8 = 4
  3. Subtract the result from step 2 (4) from 10 = 6.

  1. Money - e.g. $100
  2. Numbers used in Math - e.g. 36
  3. Horsepower and cubic inches (engine power) - e.g. 500hp
  4. Watts (sound power) - e.g. 100 watts
  5. Temperature - e.g. 70 degrees
