| Coefficient | show 🗑
|
||||
| show | A term that has only one number and no variables is called a constant, because its value doesn't vary. In the expression 2ab + 3b + 6, the number 6 is a constant
🗑

| Algebraic Expressions | show 🗑
|
||||
| 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 🗑
|
||||
| In this expression, we don't need a multiplication sign or parenthesis. Phrases like ""a number"" or ""the number"" tell us our expression has an unknown quantity, called a variable. In algebra, we use letters to represent variables. | show 🗑
|

| the product of a number and the same number less 3 | show 🗑
|
||||
| show |
🗑
|
||||
| show | x/x-5
🗑
|
||||
| The words ""divided by"" tell us we're going to divide a number by the difference of the number and 5. In this case, we'll use a fraction to represent the division. The words ""less 5"" tell us we need a minus sign because we're going to subtract five." | show 🗑
|
||||
| show | A number n times 3 is equal to 120.

| show | (a+b) + c = a + (b+c)
🗑
|

| Solving addition and subtraction equations | show 🗑
|
||||
| show | To solve a multiplication equation, use the inverse operation of division. Divide both sides by the same non-zero number.
🗑

| Solving division equations | show 🗑
|
||||
| Inequalities | show 🗑
|
||||
| show | The number (written in superscript) used to express how many times a base is multiplied by itself
🗑
