The metric system is the most widely used measuring system in the world. All major countries...You know what the equal symbol means and looks like. If a = b, then a and b are equal, (8 = 8). To learn about ordering real numbers, think about it this way. If a real number b is greater than a real number a, their relationship would look like this: −2 > −5 since −2 is to the right of −5 on the number line.What does Z mean in statistics? Simply put, a z-score (also called a standard score) gives you an idea of how far from the mean a data point is. But more technically it’s a measure of how many standard deviations below or above the population mean a raw score is. A z-score can be placed on a normal distribution curve.You are probably familiar with problems like this. 4 + 3 = _. In Algebra we might write it like this and ask the value of a instead of what number goes in the blank. a = 4 + 3. If you think that just makes it harder, I can't disagree. Even this might seem simple. 7 = 4 + _. While this seems harder. 7 = 4 + a.A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.

In elementary algebra, FOIL is a mnemonic for the standard method of multiplying two binomials —hence the method may be referred to as the FOIL method.The word FOIL is an acronym for the four terms of the product: .

If you don't use the parentheses, it will look like you mean "two cubed, times x", or 2 3 x, when you actually mean the variable to be in the exponent. x 2 y 3 z 4: x^2 y^3 z^4: Use spacing to make clear where one factor (and its exponent) ends and the next begins. Otherwise, the viewer may wonder if x^2y^3z^4 might mean something like x 2y 3z ...P(A C) or P(not A) = the probability that A does not happen. Defined here in Chapter 5. P(B | A) = the probability that event B will happen, given that event A definitely happens. It’s usually read as the probability of B given A. Defined here in Chapter 5. Caution! The order of A and B may seem backward to you at first.
