There are 320 tens in 3200.
32 tens are 320
190 + 130 = 320
320
Put 321 into three columns: Hundreds, Tens, and units. Then you have 3 Hundreds, 2 tens and 1 unit. It therefore is 320. However, if the unit was from 5 -9, you would round the ten up to 3.

If you are rounding to the nearest tens, 320 is the answer. If you are rounding up to the nearest tens, 330 would be the answer. The difference is the word "up", which specifies that the answer will be greater than 321. The answer of 320 would be rounding down.
