A coefficient is a number in front of a variable (i.e. multiplied by it). For example, in the expression x^2 - 10x + 25, the coefficient of x^2 is 1 and the coefficient of x is -10. The third term, 25, is a constant. If the expression were - x^2 + 10x + 25, the coefficient of x^2 would be -1, and the coefficient of x would be 10.
Sarin, nerve gas and mustard gas would beexamples of Chemical Warfare Agents. Sometimes, you can improveyour explanation by giving examples that are not ChemicalWarfare Agents, eg, Oxygen. These non-examples still have to havesome characteristics of the original example, but not the significant characteristic that makes the original what it is.Some educators are now calling these "non-examples." A maths teacher explaining equations might write: .
3a + 2b = 7. This is an equation. .
12 - 8. This is not an equation. .
14b - 3 = 25. This is an equation. .
150>125. This is not an equation.
Students have the potential to learn as much from the non-examplesas from the examples.
