So when Helmholtz recognized that thought moves at a finite rate, faster than a bird but slower than sound, he missed a fundamental difference between the brain and a telegraph. In our heads, speed is not always the most important thing. Sometimes what really matters is timing.
A solution of a quadratic equation is a value of the variable that makes the equation true. Many quadratic equations. can be solved by factoring and using the zero-factor property. The Zero-Factor Property: When the product of two real numbers is 0, at least one of them is 0.
Zero is an even number, because it is divisible by 2 with no remainder. 0 is neither positive nor negative. By most definitions 0 is a natural number, and then the only natural number not to be positive. Zero is a number which quantifies a count or an amount of null size. In most cultures, 0 was identified before the idea of negative things, or quantities less than zero, was accepted. The value, or number, zero is not the same as the digit zero, used in numeral systems using positional notation.
