---|---|---|---|---|---|
Additive Inverse | The number you need to add to a given number to get a sum of 0.
🗑
|
||||
Algebraic Expression | A combination of individual terms separated by plus or minus signs. It does not have an “equals” sign.
🗑
|
||||
Associative Property | If a sum contains terms that are grouped, then the sum may be regrouped with no effect on the total: a + (b +c) = (a + b) + c. If a product contains terms that are grouped, then the product may be regrouped with no effect on the result: a(bc) = (ab)c.
🗑
|
||||
Commutative Property | If two terms are added, then the order may be reversed with no effect on the total. That is, a + b = b + a . If two expressions are multiplied, then the order may be reversed with no effect on the result. That is, ab = ba .
🗑
|
||||
Evaluate | To find the numerical value of. To do this, substitute the value(s) given for the variable(s) and perform the operations according to the order of operations.
🗑
|
||||
Integers | The set of numbers {…, –3, –2, –1, 0, 1, 2, 3, …}.
🗑
|
||||
Multiplicative Inverse | For a non-zero number, it is the number we can multiply by to get the multiplicative identity, For example, for the number 5, the multiplicative inverse is 1/5.
🗑
|
||||
Numerical Term | Single numbers or products of numbers.
🗑
|
||||
Order of Operations | The order in which operations are to be carried out to evaluate or simplify expressions: parentheses, exponents (powers or roots), multiplication or division (from left to right), and addition or subtraction (from left to right).
🗑
|
||||
Quotient | The result of a division problem.
🗑
|
||||
Rational Numbers | Numbers that may be expressed in the form a/b , where a and b are integers and b ≠ 0.
🗑
|
||||
Reciprocals | The reciprocal of a nonzero number is its multiplicative inverse, that is, the reciprocal of x is 1/x.
🗑
|
||||
Simplify | To write a less complicated expression with the same value. It has no parentheses and no like terms.
🗑
|
||||
Substitution | Replacing one symbol with a number, a variable, or another algebraic expression of the same value. It does not change the value of the overall expression.
🗑
|
||||
Terms | A single number, variable, or the product of numbers and variables,
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
