WebMar 26, 2016 · When a term has a variable, it's called an algebraic term. When it doesn't have a variable, it's called a constant. For example, look at the following expression: x2y + z /3 – xyz + 8. The first three terms are algebraic terms, and the last term is a constant. As you can see, in algebra, constant is just a fancy word for number. WebWe can add several polynomials together like that. Example: Add (2x2 + 6y + 3xy) , (3x2 - 5xy - x) and (6xy + 5) Line them up in columns and add: 2x 2 + 6y + 3xy. 3x 2 - 5xy - x. 6xy + 5. …

WebIf we start with 5, for example, and then add 4, 5 + 4, then to undo that -- to get back to 5-- we must add −4: 5 + 4 + (−4) = 5 + 0 = 5. Adding −4 is the inverse of adding 4, and vice-versa. We say that −4 is the additive inverse of 4.

WebNote that this proof answers all three questions we posed. It’s the variances that add. Variances add for the sum and for the difference of the random variables because the plus-or-minus terms dropped out along the way. And independence was why part of the expression vanished, leaving us with the sum of the variances.

The reciprocal of a number is this fraction flipped upside down. In other words, the reciprocal has the original fraction's bottom number—or denominator —on top and the top number—or numerator —on the bottom. So the reciprocal of 6 is 1/6 because 6 = 6/1 and 1/6 is the inverse of 6/1. Below, you can see more reciprocals.

WebSequences and series are most useful when there is a formula for their terms. For instance, if the formula for the terms a n of a sequence is defined as "a n = 2n + 3", then you can find the value of any term by plugging the value of n into the formula. For instance, a 8 = 2(8) + 3 = 16 + 3 = 19.In words, "a n = 2n + 3" can be read as "the n-th term is given by two-enn plus … WebAug 8, 2024 · Algebraic expressions are the phrases used in algebra to combine one or more variables (represented by letters), constants, and the operational (+ - x / ) symbols.
