a squared dozen?? the printers measure is a ream
A drawing on squared paper that illustrates a concept simply.
-----------
some math equations: For area of a triangle: A=1/2 b*h. *=Times or multiplication sign. Area of a square or rectangle: A=b*h Area of a circle: A=pi R squared [try writing this one on a piece of paper. Pythagorean Theorem: a squared + b squared=c squared. perimeter: 2b+2h
that means that 50 is multiplying itself. 50x50 is the way you write it or 50^2 On paper you can write it as 502
