What is 164 rounded to the nearest 10

I think its 160 because if its 5 or more round up if 4 or less round down so 164 the 4 is less so its 160

If the ones place is below 5 it is rounded down, and if the ones place is 5 or greater you round up. 164 has 4 in the ones place, which is less than 5, so you round down to 160.

Where is the table?
