* 2 X 12 * 4 X 6 * 24 X 1
The answer is 8. Basically how you get to the solution is simple. You have to divide 24 by 6 which is 4 if you know your multiplications of 4 and then you simply times it by 2 and then you get to the answer 8! :)
No Willow Smith does not quiet now all her multiplications. She is 10 and in the 5th grade. She is, right now, as you are reading this learning her multiplications.
lower computational complexity and requires fewer multiplications
It is the associative property, according to which, you do not need to specify which of the two multiplications has to be carried out first.
1x2 2x1
3*29 = 87
It could be just the multiplications of seven for sevens
1x16, 2x8, 4x4
At most n-1. However, it can be a lot fewer. For example, calculating A10 does not require 9 multiplications. A*A = A2 A2*A2 = A4 A4*A4 = A8 A8*A2 = A10 Only 4 multiplications were required.
There are no units given for the multiplications; are they:The same unitsThe multiplications could be the areas of rectangles which means the results will be SQUARE unitswhich means if the difference required is in feet and NOT SQUARE feet, is it the difference in perimeter of the two rectangles?I think you need to re-ask your question with proper units included, then we can possibly answer it.
It depends on the expression.
Yes, unless you want divisions in the family.
