|---|---|---|---|---|---|---|---|---|
| show | A symbol or combination of symbols that represent a mathematical quantity. NOTE: The symbols can be numbers or variables, and there are NO EQUAL SIGNS within an expression. | 2x + 3
🗑
|
||||||
| LIKE TERMS | show | 7x and 5x
🗑
|
||||||
| show | A mathematical sentence in which two expressions are set equal to each other. | 2x + 3 = 5
🗑
|
||||||
| INVERSE | Opposite. | show 🗑
|
||||||
| show | An equation that is true for all real numbers. | 3x - 3 = 2x + (x - 3) is an identity, because it will simplify to the same expression on each side of the equation and work for all real numbers.
🗑
|
||||||
| ASSOCIATIVE PROPERTY | A property of real numbers that allows the changing of the grouping of addends or factors without changing the result. | show 🗑
|
||||||
| show | A property of real numbers that allows each term of an expression inside a set of parentheses to be multiplied by each term of an expression outside of the parentheses without changing the result. | For 2(3 + 5) = 2 * 3 + 2 * 5, both expressions would equal 16.
🗑
|
||||||
| show | A letter that represents a quantity or quantities. | x, y, t, n
🗑
|
||||||
| COEFFICIENT | show | For 3x, x is the variable, and 3 is the coefficient.
🗑
|
||||||
| ADDITIVE INVERSE PROPERTY | The sum of any number and its opposite is zero. | show 🗑
|
||||||
| MULTIPLICATIVE INVERSE PROPERTY | The product of a number and its reciprocal is 1. | show 🗑
|
||||||
| ADDITION PROPERTY OF EQUALITY | The property of real numbers which states that adding the same term to both sides of an equation will keep the each expression equivalent and the equation balanced. | show 🗑
|
||||||
| SUBTRACTION PROPERTY OF EQUALITY | show | For x + 2 = 3 - 4x, x can be subtracted from both sides of the equation without changing the value of it.
🗑
|
||||||
| MULTIPLICATION PROPERTY OF EQUALITY | show | For 3/5y = 10, 5/3 can be multiplied on each side of the equation without changing the value of it.
🗑
|
||||||
| show | The property of real numbers which states that dividing both sides of an equation by the same term will keep the each expression equivalent and the equation balanced. | For 35f = 105, 35 can be divided into each side of the equation without changing the value of it.
🗑
|
||||||
| INEQUALITY | show | 3x + 5 < -52
🗑
