When you estimate you round to the nearest whole number (simply to make it easier.) Depending on what place you need to estimate to (like hundreds, or just tens..)

Let's turn 196 into 200 and 482 into 480

200+480 = 680

Hope this hlps!

If u want to add them then round so 196 would be 200 and 482 would be 500 which would equal 700
