## Tags and Description

### 26 Terms

1

Variables

Letters representing unknown or changing values in algebraic expressions.

New cards
2

Terms

Numbers or letters alone or multiplied together, separated by + or - signs in expressions.

New cards
3

Expressions

Combinations of terms using + or - signs, without an = sign.

New cards
4

Equations

Two expressions set equal to each other with an = sign, indicating equal values on both sides.

New cards
5

Like terms

Terms with the same variable raised to the same power, used for simplifying expressions.

New cards
6

PEMDAS

Order of operations - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

New cards
7

Factoring

Breaking down algebraic expressions into simpler forms, often using product and sum methods.

New cards
8

Formulas

Mathematical rules using variables that are always true, allowing substitution of values.

New cards
9

Rearranging Formulas

Moving variables to one side of an equation by using opposite operations.

New cards
10

Composite Functions

Functions where the output of one becomes the input of another function.

New cards
11

Graphs

Representations of mathematical relationships on coordinate planes.

New cards
12

Transformations of Graphs

Movements of graphs vertically or horizontally, and reflections over axes.

New cards
13

Graphs of Lines

Equations in the form y=mx+c, showing slopes and intercepts.

New cards
14

Representations of equations in the form y=ax²+bx+c, including turning points and symmetry.

New cards
15

Graphs of Circles

Representations of circles with equations like (x-h)²+(y-k)²=r².

New cards
16

Graphs of Inequalities

Representations of regions where inequalities are true on graphs.

New cards
17

Solving Equations

Finding values that make equations true, often using rearrangement and order of operations.

New cards
18

Simultaneous Equations

Solving systems of equations using substitution or elimination methods.

New cards
19

Finding solutions to equations of the form ax²+bx+c=0 using factoring, quadratic formula, or completing the square.

New cards
20

Inequalities

Expressions showing relationships between values that are not equal, solved similarly to equations but with attention to negatives.

New cards
21

Sequences

Sets of numbers following patterns, including arithmetic, geometric, and linear sequences.

New cards
22

Square numbers

Numbers obtained by multiplying a number by itself, e.g., 1, 4, 9, 16, 25, 36...

New cards
23

Cube numbers

Numbers obtained by multiplying a number by itself three times, e.g., 1, 8, 27, 64, 125...

New cards
24

Triangular numbers

Numbers that can be represented as a triangle of dots, with each term obtained by adding one more than the previous term, e.g., 1, 3, 6, 10, 15...

New cards
25

Triangular numbers nth term formula

The formula to find the nth triangular number is [n(n+1)]/2.

New cards
26

Fibonacci sequence

A sequence where each term is the sum of the two preceding terms, starting with 1, 1, e.g., 1, 1, 2, 3, 5, 8, 13...
