Oh honey, it's simple math. 644, huh? Well, to round that bad boy to the nearest ten, you just look at the digit in the tens place. Since it's a 4, which is less than 5, you keep the 4 in the tens place and change the rest to zero. So, 644 rounded to the nearest ten is 640. Easy peasy lemon squeezy.
