Criteria for inclusion:Criteria for inclusion:1. Ability to isolate (brain damage; savants;

prodigies; testing; experimentation)

2. Definable set of “end-state” performances; operations (‘works’, events, rituals, etc.)

3. Susceptible to encoding (supported by symbol system – which intelligence is Braille?)

3. Thorough assessment (of understanding) is not possible if it is based on a single intelligence.






4. Most lessons are not "pure" in that they already address more than one intelligence.

4. Most lessons are not "pure" in that they already address more than one intelligence.

5. Many aspects of a lesson are also not pure : attention-getting can help learning; activities can gain attention or be used to assess; people can learn from assessments.

x0 = 1; x1 = x; x2 = x * x; x-1 = 1/x; x-2 = 1/ (x*x); leading zeros are not significant, and unless they appear to

the right of a decimal place have no effect on the value of the number

when adding and subtracting the decimal points of real numbers must be vertically aligned

when dividing two real numbers they must both be adjusted (multiplied by their base) until the divisor is an integer

for real number addition and subtraction the exponents must be the same

for real number multiplication one must multiply the mantissas and add the exponents

for real number division one must divide the mantissas and subtract the exponents
