LEQ: How can the Order of Operations be used to evaluate expressions?

Uses numbers and variables Variable: a letter used to represent an unknown number Algebraic Expression: a combination of numbers, variables and operations in a way that stands for a number. For example: 3x + 2 Algebraic Sentence: consists of expressions related with a verb. For example: 7w – 4 = 24

= (is equal to) < (is less than) > (is greater than) ≤ (is less than or equal to) ≥ (is greater than or equal to) ≈ (is approximately equal to) ≠ (is not equal to)

Equation: a sentence stating that two expressions are equal. Formula: an equation stating that a single variable is equal to an expression with one or more different variables on the other side For example: A = ½(b)(h), both an equation and formula a + b = b + a, an equation that is not a formula
