| Absolute Value | show 🗑
|
||||
| show | The numbers we use to measure real-world quantities, such as length, temperature, or volume, are called real numbers. All the rational and irrational numbers make up the set of real numbers. The number line is a model of the set of real numbers.
🗑
|
||||
| Rational Number | show 🗑
|
||||
| show | Some numbers cannot be written as a quotient of two integers, and these are called irrational numbers.
🗑
|
||||
| show | A letter that stands for a number in a mathematical expression is called a 'var'iable, because its value can vary. In the expression 4n + 7, n is a variable
🗑
|
||||
| Expression | show 🗑
|
||||
| show | in an expression, the terms are the elements separated by the plus or minus signs. In the expression 2ab + 3ab - a, the terms are 2ab, 3 ab, and a
🗑
|
||||
| show | A number that appears before a letter in a term. For example in the term 2ab, 2 is the coefficient.
🗑
|
||||
| Constant | show 🗑
|
||||
| show | An algebraic expression is one or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs. It's only a phrase, not the whole sentence, so it doesn't include an equal sign.
🗑
|
||||
| the sum of three times a number and eight | show 🗑
|
||||
| The words ""the sum of"" tell us we need a plus sign because we're going to add three times a number to eight. The words ""three times"" tell us the first term is a number multiplied by three. | show 🗑
|

| A number n times 3 is equal to 120. | show 🗑
|
||||
| This is an easy one. The word ""times"" tells you that you must multiply the variable n by 3, and that the result is equal to 120. Here's how to write this equation: " | show 🗑
|
||||
| show | a+b = b+a
🗑
|

| show | greater than
🗑
|
||||
| < | show 🗑
|
||||
| show | To solve an equation means to find a value for the variable that makes the equation true. Whatever you do to one side of the equation, you must also do to the other side. (Balance the scale)
🗑
|
||||
| Solving multiplication equations | show 🗑
|
||||
| show | To solve a division equation, use the inverse operation of multiplication. Multiply both sides by the same number.
🗑
|
||||
| Inequalities | show 🗑
|
||||
| show | The number (written in superscript) used to express how many times a base is multiplied by itself
🗑
|
||||
| show | The number directly preceeding an exponent
🗑
|
||||
| show | is a series of one or more terms that are added or subtracted, such as 3x + 2y - 4
🗑
|
||||
| show | you move the decimal point two places to the right
🗑
