Estimating/Rounding

Estimating is guessing the answer of an equation.

Example: 1254 + 308

My guess (estimation) is 1518.

Rounding is taking a number and bringing it up to the nearest tenth, hundredth, thousandth, etc. You can also bring them down if the ones place is below 5.

Examples: Rounding 78 to the nearest tenth

78 to 80

Rounding 63 to the nearest tenth

63 to 60

Is this how I'm supposed to post it...?

Sorry if I posted it wrong!
