| A | B |
| Expanded form | 50,000 + 7,000 + 300 +50 + 4 |
| exponential form | 4^5 (read "four to the fifth power") |
| base | The whole number in an exponential expression- the repeated factor |
| exponent | tells how many times the base is used as a factor |
| power | tells how many times the base is used as a factor |
| squared | a number that is multiplied by itself...the exponent of 2 |
| cubed | a number multiploed by itself, and then by itself again..."to the third power" |
| estimate | to find the approximate number or amount |
| front-end estimation | round so that the only number not 0 is the first digit (4659 becomes 5000) |
| compatible numbers | numbers that are close to the actual numbers, but are easier to compute (eg: 24x41 becomes 25 x40) |
| order of operations | PEMDAS- Parenthesis, Exponents, Multiply/Divide, Add/Subtract |
