Notes and Homework from Oct. 19 and 20th

Adding and Subtracting Decimal numbers
Estimate - to approximate an answer.
Over estimate - estimate that is larger than the actual number
Under estimate - estimate that is smaller than the actual number

Front End Estimation: that is using only the highest place value when estimating. eg. 125 + 476 = turns into 100 + 400 =
It is like under estimating.

Relative Size Estimation: rounding to the nearest highest place value.
eg. 125 + 476 = turns into 100 + 500 =
125 is between 100 and 200 but closer to 100
476 is between 400 and 500 but closer to 500
It is like rounding.

Estimating - getting an approximate answer.
Calculating - getting an exact answer.
