A solid substance that is a good conductor of heat and electricity. Can be formed into many shapes.
Metalloid
"Middle elements" - conduct heat and electricity better than nonmetals, but not as well as metals. Easier to shape than nonmetals, but not as easy as metals. Solid at room temperature.
Nonmetals
A poor conductor of heat and electricity. Not easily formed into shapes.
Figure the square root of the number you enter. Nice!
One of geometry's most useful formulas, the Pythagorean Theorem, can be applied to the numbers you enter. Just enter 'A' and 'B' and the computer solves for 'C.' Neat!
